Beyond the stars lie mysteries that twist everything we thought we understood.
Moons that fall, volcanoes that rage, and oceans concealed beneath frozen shells—each one stranger than the last.

5 Interesting Fun Facts About Planetary Moons
1. Mars’ moon Phobos is slowly moving toward the planet.
What do people usually think?
Some people believe that Phobos is gradually moving away from its planet, Mars.
You’re not going to believe it, but Phobos is not moving away from Mars; rather, it is moving towards it.
Here is the astonishing reality:
While it is true that Mars’ gravity is pulling Phobos, the distance between the two is much shorter than you think.
Phobos orbits a mere 3,700 miles (6,000 kilometers) above the surface of Mars.
Despite its size, it also exerts tidal forces on the Red Planet (Mars), which bulges by a fraction of a millimeter along the path of Phobos.
Indeed, Phobos is moving toward Mars and orbits the planet faster than Mars rotates on its axis.
2. Footprints on the Moon could last millions of years because there’s no weather.
What do people usually think?
Some people assume that astronauts’ footprints would immediately fade away, just like how our footprints are washed away by rain or wind here on Earth.
But did you know that in Moon, footprints last over a million years?
Here is the astonishing reality:
Neil Armstrong and Edwin ‘Buzz’ Aldrin were the only astronauts who landed on the Moon and left footprints, while Michael Collins remained in orbit and never set foot on the lunar surface.
According to the NASA Scientific Visualization Studio, their footprints remain to this day.
Here is why!
Without water and slow land erosion, footprints on the Moon could last for a million years.
The moon doesn’t have an atmosphere, which means there is no wind available that could erase the footprints.
