Planet in Our Solar System

What is a Planet?

Now to begin with what a planet is, it is a large, round object in space that moves around a star. For example, the Earth is a Planet in Our Solar System.

What is a Solar System?

Talking about the solar system, it consists of the Sun and the eight planets orbiting around it, including moons, asteroids, comets and meteoroids.

Planets in Our Solar System

1. Mercury: It is the smallest planet in our solar system and closest to the Sun, moreover, it is only slightly larger than Earth’s Moon. Hence, it is the fastest planet, revolving around the Sun every 88 Earth days.
2. Venus: It spins slowly in the opposite direction from most planets. A thick atmosphere traps heat in a greenhouse effect, making it the hottest planet in our solar system.

3. Earth: It is our home planet, because, it is the only planet inhabited by living things, it is also the planet in our solar system with liquid water on the surface.
4. Mars: It is a dusty, cold, desert world with a very thin atmosphere. Moreover, Mars was billions of years ago, wetter and warmer, with a thicker atmosphere.
5. Jupiter: It is more than twice as massive than other planets of our solar system combined. The giant planet’s Great Red Spot is a centuries-old storm bigger than Earth.

6. Saturn: It is a dazzling, complex system of icy rings. Hence, Saturn is unique in our solar system. The other giant planets have rings, but none are as spectacular as Saturn’s.
7. Uranus: It is the seventh planet from the Sun. Because, it rotates at a nearly 90-degree angle from the plane of it’s orbit, the unique orbit makes Uranus appear to spin on it’s side.

8. Neptune: It is the eight and most distant planet orbiting around the Sun. Talking about it’s structure, it is dark, cold and whipped by supersonic winds. In addition to this, it is the first planet located through mathematical calculations.

Facts About Pluto

While talking about Pluto, it was discovered in 1930 and is the second closest planet to the Sun and was at one point classified as the ninth planet. Moreover, it is not actually a planet but a dwarf planet consisting mostly the mass particles like nitrogen with minor amounts of methane and carbon monoxide, hence, these particles have been vaporized from their ices on Pluto’s surface.

What Astronauts Do in Space?

Talking about astronauts, they go to space to study science of planets and perform large experiments. Moreover, they observe and photograph planets especially the natural and man-made changes on Earth. Talking about the planet Earth, they also study how humans behave in isolation and confinement. In contrary to this, the easiest object to visit was the Moon. Moreover, astronauts failed to land on Mercury because it is very hot and very cold. Similarly, satellites were sent to Venus and it ate them up. People wouldn’t last long there. Talking about Mars, it takes a year to get there and is safer for landing. Hence, the rest of planets are gas giants, except Pluto, which is much colder.

Conclusion

But now to the conclusion, it is important for us to study astronomy to address fundamental questions about our place in the Universe and the history of our Solar System. Moreover, to witness frightening changes in the sky and to record movements of planetary positions it is important to study astronomy.
