Space has no oxygen.

Pluto takes 247.94 Earth years to orbit the sun. Since its discovery, it has made less than half of its orbit. Because of this long orbit, Pluto's orbit will be finished on March 23, 2178.

Space is a vacuum, which means you can't hear anything. Sound is actually vibrating air.

Due to the lack of gravity, the marble can fly without a gyrocopter and can jump so high.

Space has zero gravity. To demonstrate the lack of gravity, jump in a rising elevator (Don't try this!) and a zero-g effect will happen (Don't try this, like I said before, an alarm will be sounded. A woman got a $1100 fine.)

Btw (by the way), there are about more than 200 moons in the Solar System which orbit all planets except for Mercury and Venus.

This level resembles the eight planets. Did you know Jupiter has faint rings from its moons? Jupiter has the most moons (95 moons).

Pluto, a former 9th planet, was demoted to dwarf planet status by the IAU (International Astronomical Union) because it didn't follow the 3 criteria written. 1. Has to be in orbit around a star 2. Needs to be at least a sphere (an ellipsoid counts) 3. Must clear its neighborhood around the orbit. Pluto did not clear everything around its orbit and it is in the Kuiper Belt beyond Neptune, where there are millions of objects!
