Solar System Facts
All the planets revolve around the sun in a counterclockwise direction (as observed from a point above the north pole of the solar system).
One day on Venus is longer than one year on Venus. It is because the planet takes a longer time to rotate on its axis than to revolve around the sun.
Venus has the longest day of any planet. It takes 243 Earth days to complete one rotation on its axis.
Eris is the most massive dwarf planet in the solar system even though it is smaller than Pluto. This is because Eris is denser.
Our solar system travels at a speed of 500,000 miles per hour around the center of the Milky Way galaxy. One revolution around the Milky Way takes around 230 million Earth years.
Saturn is the planet with the highest number of moons. The planet has a total of 82 recognized moons around it.
Jupiter has the shortest day of any planet. It takes a mere 9 hours and 55 mins to rotate on its axis once.
In comparison to the other planets in the solar system, Venus and Uranus spin in the opposite direction.
Neptune's mass and orbit were calculated mathematically even before it was discovered.
Earth is the solar system's densest planet.
