Sun
Mercury is the closest planet to the sun. Its temperature can rise to at least to 400ºC and as low as -200ºC. Its revolution around the sun is 88 days. Its diameter is 3,029 miles. Its period of rotation is 58 days and its mass is .05 that of Earth's. Mercury's surface is stony and rigid deserts pocketed with craters.
Venus is the most recognizable star in the mourning and evening. Venus is 67.2 million miles away from the sun. It's revolution around the sun is 224 days. Venus has a diameter of 7,517 miles. It dates 243 days to make a rotation. Venus's mass is .81 times that of earth. Venus was named after the Roman Goddess of Love. Venus's surface is stony with large valleys, plateaus, and craters. The surface temperature can rise to 900ºC.
Earth is the only planet discovered so far to have life on it's surface. Earth was formed about 4.6 billion years ago. Earth is approximately 92,897,000 miles from the sun. Earth's diameter is 7,926 miles. The highest temperature recorded on Earth was 136ºF, and the lowest was -128.6ºF. It takes Earth 360 days to make a revolution around the sun and 24 hours to make a rotation 24 hours to make a rotation.
Mars, named after the Roman God of War is the fourth planet in our solar system. Mars is the second brightest object in the night. Mars is 142 million miles from the sun and its diameter is 4,220 miles. It takes 687 days to revolve around the sun and takes 24 hours, 37 minutes to rotate. Its mass is .11 times that of Earth. Mars's reddish glow is due to its extensive deserts covered with red sand. Mar's temperature can reach to 400ºC and drop to 200ºC. One of Mar's largest volcanoes is Olympus Mons.
Living anywhere else besides Earth is practically impossible. The son will burn you alive and the gases will kill you. The same goes on Mercury and Venus. Mercury's temperature is much too high in the daytime and too low at night. Venus's gases will also kill you and the temperature is too high. Mars might be too hot or cold, but if we build things to protect us it might be possible but doubtful.
