Other objects in the solar system include dwarf planets, asteroids and comets. Its many bodies are visible to the naked eye. Mercury, Venus, Earth and Mars are the small rocky planets. Jupiter, Saturn, Uranus and Neptune are the gas giants. The sun is by far the largest object in the solar system.

All the planets orbit the sun in an eliptical, oval shaped path. In the galaxy, the Solar system is known as “The Milky Way”. Astronomers have found many other stars in our galaxy which have planets orbiting around them. There are around 200 billion stars in the milky way. The Voyager 1 spacecraft is the furthest man-made object in the solar system, it is around 11 billion miles (18 billion km) from the sun and is still sending data back to Earth.
