20 facts of Solar System

1. The “Great Red Spot” on Jupiter is a large high-pressure area twice the size of the Earth. It is the largest hurricane in the solar system and is believed to have existed for over 400 years. Want to read more about Jupiter? Check out our Jupiter facts!

2. Scientists assume that Venus once offered Earth-like conditions and even had oceans. However, the extreme greenhouse effect caused a sharp rise in temperature, so that the water finally evaporated.

3. Around four billion years ago Mars had an oxygen-rich atmosphere.

4. On Jupiter’s moon Europa, there is probably an ocean under a thick layer of ice that holds more water than the oceans of the Earth combined. Scientists believe it may even contain microbes.

5. The Moon is in synchronous rotation with Earth meaning the Moon rotates around on its own axis in exactly the same time it takes to orbit the Earth. As a result, the Moon always shows Earth on the same side.

6. Most of the moons orbiting around Uranus are named after characters that appeared in the works of William Shakespeare and Alexander Pope. Those named after characters from Shakespeare include Titania, Oberon, and Puck from “A Midsummer Night’s Dream” and Ariel and Miranda from “The Tempest”.

7. The rings of Saturn consist of thousands of ringlets.

8. Saturn’s rings consist of ice, dust, and stone. While some components are only as large as grains of sand, others are up to more than half a mile (one kilometer) in diameter.

9. More than one million planet Earths would fit inside of the sun. The sun is an object that is so impressive that we really had to research more facts about the sun.

10. On Venus, a day is shorter than a year. Because of its low rotational speed, it takes longer to rotate on its own axis than to orbit the Sun.

11. Geographical features on Mars are named in a special way. Craters that are smaller than 30 miles (50 kilometers) are named for towns and villages of the world with a population of less than 100,000 people whereas craters larger than 30 miles are named for deceased scientists and writers who have contributed to the study of Mars. Large valleys are named for the word “star” or “Mars” in various languages and small valleys are named for rivers.

12. In the core of Jupiter, it is hotter than on the solar surface.

13. With 82 moons, Saturn has the most moons in our solar system. Jupiter is second with 79 moons.

14. When Pluto has circled the sun once, 1028 years have passed on Mercury. Although Pluto is not a planet anymore, there are many facts about the dwarf planet to discover, as Only fun facts.

15. Jupiter’s moon Ganymede is the largest moon in the solar system. With a diameter of 3,273 miles (5,268 kilometers) it is even larger than the planet Mercury.

16. Our solar system is estimated to be 4.6 billion years old.

17. Mercury has at the tail of rock particles. Scientists are still unsure, how to explain that phenomenon.

18. Although the moon is not the largest satellite in the solar system it is the biggest in relation to the planet it orbits.

19. There is water ice on Mercury.

20. Since 2006 Pluto is officially no longer a planet since the dwarf planet Eris was discovered in 2005. Although it is slightly smaller than Pluto, it is more massive. This led to a revision of the planet definition, which then no longer applied to Pluto. Because scientists assumed that in the future further planets of this size could be discovered.

How old is our solar system?

According to the Space, Meteorites, or pieces of space rock that have fallen to Earth, have helped scientists figure out the age of the solar system. Some of these small pieces of space rock, or meteoroids, have broken off moons or planets, and can yield interesting scientific information about the chemistry and history of their homebody; others have been traveling around our solar system since that primordial dust-cloud collapse before those planets even existed. The Allende meteorite, which fell to Earth in 1969 and scattered over Mexico, is the oldest known meteorite, dated to 4.55 billion years old.
