Planets in the Solar System
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.
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 only left over water is frozen ice caps or underground. Mars interests scientists because of mild climate and its similarities to Earth.
Jupiter is the fifth planet from the Sun. It is the largest planet in the solar system. It has the shortest day out of all the planets in the solar system. Its day is 9 hours and 55 minutes. Its year is about 4333 days. Jupiter has no solid surface. Under its atmosphere is an ocean of hydrogen and water. As is sky condenses it slowly becomes part of the ocean.
Saturn is the sixth planet from the Sun. It is the second largest planet in the solar system. Its day is 10 hours and 13 minutes. Its year is about 10,800 days long. Saturn is the planet with the most amounts of moons. It has 34 moons.

The Sun is roughly middle-aged; it has not changed dramatically for more than four billion[a] years, and will remain fairly stable for more than another five billion years. It currently fuses about 600 million tons of hydrogen into helium every second, converting 4 million tons of matter into energyevery second as a result. This energy, which can take between 10,000 and 170,000 years to escape from its core, is the source of the Sun's light and heat. In about 5 billion years, when hydrogen fusion in its core has diminished to the point at which the Sun is no longer in hydrostatic equilibrium, its core will undergo a marked increase in density and temperature while its outer layers expand to eventually become a red giant. It is calculated that the Sun will become sufficiently large to engulf the current orbits of Mercury and Venus, and render Earth uninhabitable. After this, it will shed its outer layers and become a dense type of cooling star known as a white dwarf, and no longer produce energy by fusion, but still glow and give off heat from its previous fusion.
