It is not possible to see two moons of the same size and shape in the night sky. The moon is Earth's only orbiting satellite, and it is the closest celestial body to Earth, making it the brightest object in the night sky.
If the night sky appears to have two moons, the second celestial body could be another planet in the solar system, such as Mercury, Venus or Mars. However, those planets are located much farther away from Earth than the Moon, making them appear much smaller in size in relation to the Moon. Seeing two moon-sized celestial bodies in the night sky is not possible.
