Is alpheratz bigger than the sun?
Distance, Size, and Mass The primary star designated as Alpheratz A has around 3.8 solar masses, or 380% of our Sun’s mass, and 2.7 solar radii, or 270% of our Sun’s radius. It is thus more than 5 times bigger than our Sun. It is three times bigger than our Sun.
What constellation is Almach in?
constellation Andromeda
Almach is one of the brightest stars of the constellation Andromeda, the princess. It’s about half-way up the northeastern sky as night falls, and passes high overhead in the wee hours of the morning. The system is about 350 light-years away. At that great distance, the eye alone sees only a single pinpoint of light.
How big is the Gamma Andromedae star system?
It is a multiple star system approximately 350 light-years from the Earth. The system is drifting closer to the Sun with a radial velocity in the range of −12 to −14 km/s. In 1778, German physicist Johann Tobias Mayer discovered that γ Andromedae is a double star.
Which is the brighter member of Gamma Andromedae?
The brighter member, γ 1 Andromedae, is the primary of the system, and is thus designated component γ Andromedae A. It has the official proper name Almach / ˈælmæk /, which was used as the traditional name of the naked eye star, and thus the system as a whole. The fainter secondary is γ 2 Andromedae or γ Andromedae B.
How big is Alpha Andromedae compared to the Sun?
The larger, brighter star, called the primary, has a spectral type of B8IVpMnHg, a mass of approximately 3.6 solar masses, a surface temperature of about 13,800 K, and, measured over all wavelengths, a luminosity of about 200 times the Sun ‘s.
Which is closer to US Almach or Gamma Andromedae?
The system is closer to us than Gamma Andromedae A, lying at a distance of about 260 light years. Gamma Andromedae B and Gamma Andromedae C orbit each other with a period of 63.67 years at an average separation of only 0.3 arcseconds (33 astronomical units).
