Can moons have moons?

What happens if the Moon crashed into Earth?
With the Moon coming closer, Earth’s rotation would speed up. Our days would become shorter and shorter. Global temperatures would go down, nobody would worry about climate change anymore. Unless asteroids burned the Earth to a crisp.
Why is the Moon red?
Blood moon
As sunlight penetrates the atmosphere of Earth, the gaseous layer filters and refracts the rays in such a way that the green to violet wavelengths on the visible spectrum scatter more strongly than the red, thus giving the Moon a reddish cast.

Can you fart in space?
Therefore, the fart will not be smelled by the astronaut, although they may marinate in it for a time. When astronauts are not in the space suit and floating about, the fart smell is exaggerated by the lack of airflow from the recycled air used and its inability to mask any smell. … Same goes in space.
