Mercury is the closest planet to the Sun and the smallest in our Solar system. With an average distance of 58 million kilometres from the Sun, Mercury orbits around it in 88 Earth days. Venus is the second planet from the Sun and is sometimes known as the Earth's "twin", because the two planets are so similar in size. The diameter of Venus is about 12,100 kilometres, approximately 644 kilometres smaller than that of the Earth. With an average distance of 108 million kilometres from the Sun, Mercury orbits around it in 225 Earth days. Earth is the third planet from the Sun and the place we all call home. With an average distance of 150 million kilometres from the Sun, Earth orbits around it in 365.25 days. Mars is the fourth planet from the Sun and one of Earth’s next door neighbours in space. With an average distance of 228 million kilometres from the Sun, Mars orbits around it in 687 Earth days. Jupiter is the fifth planet from the Sun and is the largest planet in our Solar system. About 11 times wider than Earth, Jupiter has a diameter of 142,984 kilometres. With an average distance of 778 million kilometres from the Sun, Jupiter orbits around it in 11.86 Earth years. Saturn is the sixth planet from the Sun and is the second largest planet in our Solar system. Saturn has seven thin, flat rings around it that are made up of ice particles travelling around the planet. With an average distance of 1.42 billion kilometres from the Sun, Saturn orbits around it in 22.46 Earth years. Uranus is the seventh planet from the Sun. It is the farthest planet that can be seen without a telescope. With an average distance of 2.87 billion kilometres from the Sun, Uranus orbits around it in 84 Earth years. Neptune is the eighth planet from the Sun. It is the only planet in our system that cannot be seen without a telescope (excluding Pluto). With an average distance of 4.49 billion kilometres from the Sun, Neptune orbits around it in 165 Earth years.
