Why is Upsilon Andromedae famous?
All three are comparable to Jupiter in mass. Upsilon Andromedae was both the first multiple-planet planetary system to be discovered around a main sequence star, and the first multiple-planet system known in a multiple star system.
What type of star is Upsilon Andromedae?
Upsilon Andromedae A is a yellow-white dwarf of spectral type F8V, similar to the Sun, but younger, more massive, and more luminous. According to its entry in the Geneva–Copenhagen survey, the star is around 3.1 billion years old and has a similar proportion of iron relative to hydrogen to the Sun.

How many planets are in Andromeda?
Currently we estimate that at least 50% of all stars are orbited by at least one planet – most likely the fraction is even higher. Taking this number, and the estimated number of stars in the Andromeda Galaxy into account, there are 500 billion planets in Andromeda.
What is unique about the star Upsilon Andromedae?
Its discovery made it the first multiplanetary system to be discovered around a main sequence star, and the first such system known in a multiple star system. The exoplanet was found by using the radial velocity method, where periodic Doppler shifts of spectral lines of the host star suggest an orbiting object.
Can we live in the Andromeda Galaxy?
Would life be possible in the Andromeda galaxy? – Quora. Originally Answered: Is it possible there is an Earth-like planet that hosts intelligent life like our own in the Andromeda Galaxy? Yes, it’s possible. Given that it contains more than twice as many stars as our own galaxy, it may even be more likely.

What kind of star is Upsilon Andromedae?
Upsilon Andromedae is a binary star located approximately 44 light-years from Earth in the constellation of Andromeda. The system consists of an F-type main sequence star and a smaller red dwarf star. Upsilon Andromedae is the star that Britomartis orbits, along with Majriti .
What was the distance of the Andromeda Galaxy?
Distance to Andromeda. Astronomers Heber Curtis proposed that Andromeda was a separate “island universe”, located about 500,000 light-years away. Edwin Hubble ended the controversy once and for all in 1925 when he identified Cepheid variable stars in Andromeda, and calculated that the galaxy was actually 1.5 million light-years away.
Which is closer to Earth Andromeda or Magellanic Cloud?
There are several galaxies closer to Earth than Andromeda. The Large Magellanic Cloud is only 160,000 light years away, and the Canis Major Dwarf Galaxy is a mere 25,000 light-years from Earth. But Andromeda is the largest grand spiral galaxy to us.
When did Edwin Hubble calculate the distance to Andromeda?
Edwin Hubble ended the controversy once and for all in 1925 when he identified Cepheid variable stars in Andromeda, and calculated that the galaxy was actually 1.5 million light-years away. Modern astronomers are continuing to calculate the distance to Andromeda.
