What does Right Ascension mean?

Answer 1

Right ascension is essentially the longitude on a star chart where you may look to find something in the sky among the stars. The distance of a point east of the First Point of Aries, measured along the celestial equator and expressed in hours, minutes, and seconds.

Answer 2

Right Ascension is a celestial coordinate that measures the eastward angular distance of a celestial object from the vernal equinox, along the celestial equator. It is similar to longitude on Earth but is used in astronomy to pinpoint the position of stars and other celestial objects in the sky. Right Ascension is typically measured in hours, minutes, and seconds.
