According to radiometric dating and other sources of evidence, Earth formed over 4 billion years ago.]]> 2018-01-11 16:35:45 UTC https://padlet.com/3097213/riin3jrlp53n/wish/220664828 3097213 https://padlet.com/3097213/riin3jrlp53n/wish/220664902 Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, Mars carries a name of the Roman god of war, and is often referred to as the "Red Planet" because the reddish iron oxides prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye.]]> 2018-01-11 16:35:51 UTC https://padlet.com/3097213/riin3jrlp53n/wish/220664902 3097213 https://padlet.com/3097213/riin3jrlp53n/wish/220664963 Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. It has the longest rotation period of any planet in the Solar System and rotates in the opposite direction to most other planets. It has no natural satellites.]]> 2018-01-11 16:35:57 UTC https://padlet.com/3097213/riin3jrlp53n/wish/220664963 3097213 https://padlet.com/3097213/riin3jrlp53n/wish/220665033
Mercury is the smallest and innermost planet in the Solar System. Its orbital period around the Sun of 88 days is the shortest of all the planets in the Solar System. It is named after the Roman god Mercury, the messenger to the gods. Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, so it can only be seen visually in the morning or the evening sky, and never exceeds 28° away from the Sun.

It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process.^[16] It is by far the most important source of energy for life on Earth. Its diameter is about 1.39 million kilometers, i.e. 109 times that of Earth, and its mass is about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.^[17] About three quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron.^[18]]]> 2018-01-11 16:36:11 UTC https://padlet.com/3097213/riin3jrlp53n/wish/220665086
