The Solar System

The Solar System

Space is vast with clusters of stars. One of those stars is our very own Sun! What revolves around our sun is planets and dwarf planets. Our most know space objects that rotate around our sun is Mercury, Venus, our home planet Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and that dwarf planet Pluto. All the space objects make up our #SolarSystem. Here is some cool facts about each of them!


The Sun
  • When all the Hydrogen has been burned, the Sun will continue for about 130 million more years, some point it will engulf Mercury and Venus and the Earth. This stage means it's a Red Giant.
  • At around 4.5 billion years old, the Sun has already burned off about half of its store of Hydrogen. The Sun is currently a Yellow Dwarf.
  • The mass of the Sun is approximately 330,000 times greater than that of Earth. It is almost three quarters Hydrogen, whilst most of the remaining mass is Helium.


  • The sun's rays are about seven times as strong on Mercury as they are on the Earth.
  • Mercury has virtually no atmosphere. It however has small traces of an atmosphere which consists minute quantities of Hydrogen, Oxygen, Sodium, Potassium and argon.
  • Mercury is the second densest planet.


  • Planet Venus is named after the Roman goddess of love and beauty.
  • Venus is one of the brightest objects in the sky, next to the Sun and Moon.
  • Venus has a longer day than it does a year.

#Earth (#HOME)

Our home, Earth
  • The Earth weighs 6,588,000,000,000,000,000,000,000 tons.
  • The temperature of the Earth's interior increases by 1 degree every 60 feet down.
  • The world is not round. It is an oblate spheroid, flattened at the poles and bulging at the equator.


  • One of Mars' moons, Phobos, is moving closer and closer to Mars. Scientists think that one day it will crash into Mars.
  • The thin atmosphere of Mars is made of mostly carbon dioxide.
  • In 1996 NASA, while studying the ALH 84001 meteorite of Martian origin found in Antarctica in 1984, announced that fossilized micro-organisms from Mars might be present in it.


  • Jupiter rotates faster than any other planet in the Solar System.
  • It rotates so quickly that the days are only 10 hours long, but it takes 12 Earth years for Jupiter to complete an orbit around the sun.
  • The Great Red Spot on Jupiter is a storm that has been going on for over 300 years.


  • Saturn's rings are made up of billions of pieces of rocks and dust.
  • Galileo was the first astronomer to observe Saturn's rings.
  • Titan is the only Saturn Moon with an atmosphere...Titan is also larger than the planet Mercury.


  • It takes 30,685 Earth days for Uranus to complete an orbit around the sun.
  • Uranus has 27 known satellites.
  • Because of the way Uranus spins, nights can last up to 40 years on some part of the planet!


  • Neptune is the stormiest planet. The winds there can blow up to 1,240 miles per hour, that is three times as fast as Earth's Hurricanes.
  • Neptune has 19 known moons.
  • It goes around the sun once every 165 Earth Years.


  • Pluto is smaller than the Earth's moon.
  • Pluto was discovered in 1930 by Clyde Tombaugh.
  • Technically, Pluto's name is now 134340 after being classified as a dwarf planet.
