Our Solar System is the planetary system bound by the gravitation of the Sun and all the bodies that revolve around it, either indirectly or directly. The bodies that revolve around the sun indirectly are the moons and the bodies that revolve around the sun directly are called planets, large and dwarf and all other objects in the solar system.

Speech on Solar Systems and Planets 1

Respected Principal Sir, Respected Teachers, all other members of the School and My Fellow Students!

First of all, I would like to welcome you all to the Science Fair that is conducted every year in our school. It started when I was in Standard V, since then I have been an active participant of the Science Fair. Every year, on the first day of the Fair, the school shares some surprises and exciting news with us.

This year, our school has something very enjoyable and exciting for us, especially for the small students. This year, our school has decided to take all of us to the Science Museum and the Planetarium on the last day of the Fair. Exciting, isn’t it? Personally, I am very enthralled and excited as knowing about the Solar system and the Planet has always been one of my favorite fascinations.

We all know that our Solar System is constituted of the 8 planets that revolve around the Sun. However, how many of you know that, along with the planets, the Solar System has the comets, moons, minor planets, asteroids, gas and dust, etc. as well. The internal part of the solar system has the Sun, Venus, Mercury, Mars and the Earth. The principal asteroid belt stretches out between the ranges of Jupiter and Mars.

The planets that lie in the external layer of the solar system include the Saturn, Jupiter, Neptune and Uranus. Many of you might be wondering why haven’t I taken the name of Pluto or in fact, many of you must be aware that Pluto is considered as ‘Dwarf planet’ now since it does not meet the criteria and definition of being a ‘Planets’ as per the new classification shared by the IAU (International Astronomical Union).

Each and everything within the Solar System revolves around the Sun and the Sun has approximately 98% of entire material within the Solar System. This is because any object that is very big in size would have more and more gravity and since the Sun is so huge, its strong gravity pulls all the other objects within the Solar System towards itself.  On the other hand, all the objects that are moving in high speed make constant attempt to move away from the Sun, into the empty part of the outer space of the solar system.

As a consequence of the planets’ attempt to move away and the Sun’s attempt to draw them inward, the planets get stuck somewhere in between. They usually get balanced between the ‘escape from the sun’ and ‘getting drawn towards the Sun’, these planets spend their entire life revolving around the sun.

Well, there are a lot of other things to know about our solar system and the planets. The visit to the Science Museum and the Planetarium will be a great opportunity for all of us to know about all these, in group. I am really thankful to the school for giving us this learning and enriching opportunity.

I would rest my speech here anticipating that our trip to the planetarium would one of the best learning experiences for all of us!

Thank you!


Speech on Solar Systems and Planets 2

Dear Students – A very good morning to all of you!

Hope you all are settled. It gives me immense pleasure to welcome you to the 5th Science Fair of our school. Without taking much of your time; I would like to tell you that the theme for this year’s Science Fair is ‘Solar System and the Planets’.

You all are aware that our solar system consists of eight planets along with their respective moons and the satellites, and all these revolve constantly around the Sun. Many of you, I am sure know that Pluto is now considered a ‘Dwarf Planet’ while it was one of the planets in earlier days. The remaining eight planets include Mercury; Venus; Earth; Mars; Jupiter; Saturn; Uranus, and Neptune. Pluto, in earlier times was the smallest and the ninth planet of our solar system but International Astronomical Union (IAU) changed the description of the planets and since Pluto was not meeting the required standards; it is considered as the ‘Dwarf planet’ now.

The planet Mercury is the closest planet to the Sun and it is also the tiniest planet in the entire solar system. Being closest to the Sun, it has the smallest year compared to all other planets. However, its day is longer than its year and 1 year of Mercury is equal to approximately 88 days of the earth; that is the smallest in the whole solar system.

You all might have heard about the leap year; the year in which February month has 1 day extra i.e. 29 days. Leap year comes every fourth year. Did you ever wonder why it is so? Our Solar system and the planet Earth have the response to this question. Earth is the only planet that is inhabited with living beings. 1 day on Earth consists of 23 hours & 56 minutes and a year on the planet is 365.3 days. Every 4th year the 0.3 gets added up that makes an extra day and called as Leap Year, well known as February 29th.

All planets have their own importance and interesting stories. I am sure you all know that Jupiter is the biggest planet in the entire Solar system and is positioned fifth from the Sun. The planet has the smallest day compared to all other planets, i.e. is 9 hours, 55 minutes only. However, its year has approximately 4333 days, maximum of all the planets. Since Jupiter does not have any solid surface; survival of life is not possible on this planet. The atmosphere of Jupiter contains a huge ocean of water and hydrogen and as the sky compresses, it gradually becomes the element of the ocean making the ocean larger.

Well there are lots of other interesting things to know about our Solar system and the Planet. While Internet is the highly resourceful in gaining knowledge about it; I would recommend that you should study books and articles published in the Newspaper, etc. to gain better understanding about the Solar system and the Planet.

Thank You!


Speech on Solar Systems and Planets 3

Dear Teachers and Students,

This is a great occasion and I am feeling highly honored for having been called to share my learning experience with you all. I had studied from this esteemed institution and after my schooling, I took up to studying Astronomy and now I am a Scientist with R&D Center, New Delhi.

While the school has inculcated in me, discipline and interest towards studying the Solar system and planets, Galaxy, etc. I believe my passion towards studying the Moon, Stars, Solar system, and the Galaxy had been instrumental in making me a successful student.

Our Solar system is so vast and enormous that the more you learn about it, the more deeply you get involved in it. Ever since its discovery in the year 1930, Pluto had been considered the 9th planet and the smallest planet in or Solar system. However, this notion started changing towards the end of 1990s, when Scientists and astronomers started arguing about the Pluto not being a planet in all respect. In the year 2006, the IAU (International Astronomical Union) finally made a decision remove Pluto from the list of the planets and named it as ‘Dwarf planet’ and thus we are now left with 8 ‘actual planets’ in the Solar system.

As you all know that the 8 planets are Mercury that is the smallest planet and nearest to the sun. Venus is the hottest planet and nearest to our Earth. Earth is the only planet that is inhabited by living beings. Mars is the second smallest planet; Jupiter is the biggest planet with maximum number of Moons. Saturn is the second largest planet; then come Uranus and Neptune; these are farther from the sun.  While Mercury; Venus; Earth and Mars are the interior rocky planets; the Jupiter and Saturn are the exterior gas giant planets and Uranus and Neptune are the exterior ice giant planets.

All the planets are part of our Solar System and continuously revolve around the sun. Our planet Earth takes approximately 24 hours to revolve on its axis, causing the occurrence of day and night; and it takes approximately 365 days to orbit the sun. Not only by the Earth, the Sun is been orbited by all other planets, comets, asteroids and all other objects in the Solar system.

You would be amazed to know that our Solar System is approximately 4.6 billion years old and is created by the gravity in a huge molecular cloud. Are you aware that the Sun we see is actually a huge star, made up of helium and hydrogen and contains approximately 99.9% of the entire Solar System’s mass. This is why it has enormous gravity that pulls everything towards self causing every object in the planet to revolve around it.

Our Solar System also has other objects such as asteroids, lies somewhere in between Jupiter and Mars. Other objects such as the ‘Kuiper belt’ and the ‘scattered disc’ surround Neptune. All these locations have dwarf planets such as Pluto and others. There are various other very tiny particles and objects in all these areas such as centaurs, comets, interplanetary dust, etc.

Well, the solar system is very huge and it is not possible for anyone to share everything about it in discussions. I would recommend those who are interested in knowing more about the planet must study books, articles, etc.

You may also get in touch with me,

Thank you!


Speech on Solar Systems and Planets 4

Respected Principal Sir, Respected Teachers and My Dear Students!

It is an immense pleasure to stand amidst you and sharing my experience of studying Astronomy with you all. Until 3 years back, I was one of you. After passing out my Secondary exams from the school, I took up to study Astronomy as Solar System, Planets, Sun, Moon and Stars have always fascinated me.

Most of us have seen in our childhood and even as grown up adults – moons, planets and sun from various viewpoints at different times of the day. I have found out that there is a lot to learn and gain knowledge from our Solar System. Our Solar System is so huge and vast, that one can never learn everything about it. However, it is always good that one starts from the basics; for learning about the galaxy, planets and the Solar system, it is important that one learns about the physical factors of the solar system. In order to do so, one must enroll to institutes that trains and teaches about the Solar System.

When I was a kid, I was highly mesmerized about the stars, planets, sun and the Solar system. I wanted to view them closely; my father then bought me a telescope. When I grew up, he gave me a special camera that can click pictures of these bodies from different angles. Now when I am studying astronomy, I have found out that certain types of ‘Robots’ are also involved in studying the solar system. The most basic thing about the Solar system is that there are 9 planets in the solar system, namely: Mercury, Venus, Earth, Mars, Saturn, Jupiter, Uranus, Neptune and Pluto. In fact, I have grown up knowing that fact. But recently, Pluto’s name has been removed from the list of Planets as Pluto doesn’t meet the new criterions that define the planets. Hence, Pluto is now only a ‘Dwarf Planet’.

We all know that Sun is the source of light and heat; but did you know that the Sun is made up of almost 98% of hydrogen and helium and comprises nearly every type of substances in the Solar System. Therefore, the Sun produces light and heat for the entire Solar System. Planets and objects that are nearer to the Sun are greatly made up of substances with greater melting points and thus have barren surfaces in higher ratio.

While, objects and planets that are distant from the Sun are usually made up of substances with lesser melting points. Therefore, life and survival is possible on such planets. However, Earth is the only planet where water is found; therefore making survival of living beings only possible on Earth. The composition of the Solar system includes the Sun in the middle, four giant planets and four inner planets bordered by the ‘Kuiper belt’, which is typically made of icy objects.

Well friends, I am sure you all have been mesmerized hearing about the Solar system so far. However, there is a lot to know about the galaxy, Solar System, Planets and the whole Universe.

I would recommend, if anyone of you is extremely interested to know more about these, may contact me personally or read books published on the Solar System.

Thank you for hearing me out!
