Sound travels on Earth through vibrations in the air, which is missing in outer space and hence, there is complete silence.
Since there is no atmosphere on the moon, so it has no breeze which can slowly erase footprints.
If we consider sun to be an empty ball, it will be able to fit 1.3 million Earths inside it.
The distance between the Earth and moon becomes so vast when it is at apogee, which is the farthest point from Earth, that all the planets can fill in.
Jupiter has been called the ‘vacuum cleaner of the solar system’ because it eats up asteroids or comets which come nearby due to its strong gravitational force and hence, stops them from colliding with Earth.
The scientific term for this phenomenon is ‘spaghettification’, and it occurs when gravity stretches a human in one direction and squeezes in another.
Light takes a long time to reach Earth and by the time we witness the light from the stars, years pass by. How much back in time we are seeing depends on how far away we are from the star.
