About Planets

 1. There are total Eight planets in our Solar system :  Mercury , Venus, Earth , Mars, Jupiter , Saturn, Uranus, Neptune.

2.The inner, rocky planets are Mercury, Venus ,Earth and Mars

3. The outer planets are gas giants Jupiter and Saturn and Ice giants Uranus and Neptune.

4.Mercury : Mercury is the smallest planet in our solar system and it is closest to the sun.It is only slightly larger than Earth's moon. Mercury is the fastest planet, zipping around the sun every 88 Earth  days.

5.Venus is the second planet from the Sun and is Earth’s closest planetary neighbor.

6. Venus has a thick, toxic atmosphere filled with carbon dioxide and it’s perpetually shrouded in thick, yellowish clouds of sulfuric acid that trap heat, causing a runaway greenhouse effect.

7.Another big difference from Earth – Venus rotates on its axis backward, compared to most of the other planets in the solar system. This means that, on Venus, the Sun rises in the west and sets in the east, opposite to what we experience on Earth.

8.While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus.

9.The name Earth is at least 1,000 years old. All of the planets, except for Earth, were named after Greek and Roman gods and goddesses. However, the name Earth is a Germanic word, which simply means “the ground.”

10.Earth is the perfect place for life as we know it.

11. Mars is the fourth planet from the Sun – a dusty, cold, desert world with a very thin atmosphere.

12. Jupiter is a gas giant and so lacks and earth like surface. It it has a solid inner core at all, its likely only about the size of the earth.

13. Saturn's atmosphere is made up mostly of hydrogen(H2) and helium(he).

14.Like venus , Uranus rotates east to west. But uranus is unique in that it rotates on its side. 

15.Dark, cold and whipped by supersonic winds, ice giant Neptune is the eighth and most distant planet in our solar system.
