Constellations are a imaginary pattern of Stars that are in the night sky created by many people. Constellations were known to be dated in Pre-History (which is also known as Before Christ, or BC) or in Greek Mythology. Known constellations are
Pisces, Orion, Ursa Major/Minor, Aries,
Virgo, Scorpius, Sagittarius, and a lot more, being about 88 constellations in the night sky. These constellations used to be a little bit unrecognizable in the years of 100,000-
25,000 BC, and
will become unrecognizable in the future approximately 65,000-125,000 years from
now due to the movement of stars due to no gravity in space.
