Whether the Moon rotates on its own axis?

Some people believe that the Moon doesn't rotate because it is always turned to us on one side. That’s a misconception.

It is the fact that the Moon always faces one side of the Earth as it orbits the Earth that indicates that the Moon rotates. And the time of one revolution around its axis is exactly equal to the time of one revolution around the Earth.
It is the so-called synchronous rotation, caused by the tidal forces of the planet.

Colour of Star As a Function of Temperature

☁️ In space, there exists an intergalactic cloud of gas and dust called Smith's Cloud, which is moving at a speed of about 240 km/s and is believed to have first entered the gravitational influence of the Milky Way approximately 70 million years ago.

What is the minimal size of black holes?

The mass of a black hole formed by the collapse of a larger star is limited by the Oppenheimer-Volkoff limit. Its exact value is not known, as it depends on many poorly understood parameters. In general, this limit lies between 2.14 and 2.17 solar masses.

All stars lighter than 2.14 solar masses are definitely not black holes. The highly probable BH candidates known today have significantly higher masses, from 6 solar masses and higher.

For primary (small) black holes to lower value is the Planck mass: 2.176⋅10^(-8) kg. But primary black holes are hypothetical objects and have not been discovered yet.
