Our solar system has eight planets, their moons and satellites, and they are all orbiting the Sun. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto used to be the ninth planet but IAU changed the definition of planet and Pluto did not meet the standards so it is now a Dwarf planet.
Mercury is the first planet closest to the Sun. It is the smallest planet in the solar system. Mercury rotates three times in two of its years. One of Mercury's days is equal to 176 Earth days because its rotation is very slow. What is weird is that its day is longer than its year. Mercury’s year is about 88 earth days the shortest in the solar system. It has the shortest year because it is closest to the Sun.
Venus is the second planet closest to the Sun. It is the sixth largest planet in the solar system. A day in Venus lasts 243 days in earth years. One year on Venus is about 224 Earth days. Venus is the hottest planet in the solar system with an average of 840 degrees Fahrenheit.
Earth is the third planet closest to the Sun. It is the fifth largest planet in the solar system. Everyone thinks that a day on Earth is 24 hours. That is actually incorrect. A day on Earth is 23 hours and 56 minutes. A year on Earth is 365.3 days. Every 4 years the three gets counted up. Then it is made into a day called a leap year. The leap year day is February 29th.
Mars is the fourth planet closest to the Sun. It is the seventh largest in the solar system. A day on Mars is equal to 24 hours and 37 minutes the closest to Earth’s day. A year on Mars is equal to about 687 days. There is evidence of rivers, lakes, streams, and oceans that evaporated on Mars. The...
