Facts About Solar System PlanetsHelp for Science Projects and Reports
Here are some facts to help you out when teaching or learning about the planets in our solar system. There may even be a 10th planet coming soon!
There are currently nine planets in our solar system. Each planet orbits around the Sun. When a planet makes a complete path around the Sun, it is called a revolution. Our planet, Earth, takes approximately 365.25 days to make a revolution. Planets that are farther away from the Sun take longer to make a revolution. Planets spin on an axis, which is an imaginary line that goes through the center of the planet. The time it takes Earth to rotate on its axis equals one day or 24 hours. Here are some interesting facts about each of the planets: (Day = midday to midday) Mercury
