Where can I find Alpheratz?
Autumn is a good time to look. People often find the Andromeda galaxy by star-hopping from Alpheratz to two other stars in the constellation Andromeda, Mirach and Mu Andromedae. After you find those two stars, you can draw a line between them, and extend that line to find the galaxy, as shown in the chart above.
How many light years would it take to get to Alpheratz?
Distance from Earth Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 33.60000 which gave the calculated distance to Alpheratz as 97.07 light years away from Earth or 29.76 parsecs.
Why is Arcturus so bright?
When Arcturus’ supply of hydrogen was fully depleted, it transitioned into its red giant status and astronomers believe it is now fusing helium into carbon in its core instead (which helps explain why it shines brightly and produces so much heat).
Is alpheratz a blue giant?
Alpheratz is a binary star with an apparent magnitude of +2.06. It is a hot blue star classified as a B8 subgiant. The brighter of the two stars in the binary system has an unusual chemical composition, with unusually high levels of mercury, manganese, and other elements.
