WebAccording to NASA, Space Exploration and Astronomy News Rigel is 863 light years away. Betelgeuse is almost in the same direction but only 548 light-years away but that is uncertain by as much as 100 light-years because Betelgeuse is a pulsating star getting brighter and dimmer. But a good guess is that it is another 315 light years to Rigel. WebLimitations of Distance Measurement Using Stellar Parallax Parallax angles of less than 0.01 arcsec are very difficult to measure from Earth because of the effects of the Earth's atmosphere. This limits Earth based telescopes to measuring the distances to stars about 1/0.01 or 100 parsecs away.
Web4 aug. 2024 · Near to Earth, relatively speaking, far away of approximately 550 light-years, Betelgeuse is what is known as a semi-regular variable star.
