Why does the alpha centauri star not look as big as the sun?

It looks smaller than the sun because it is much farther away.


The star closest to Earth 4.2 light years?

The closest star to Earth is Proxima Centauri, which is a binary star with Alpha Centauri. Proxima Centauri is too small to be seen without a telescope, and Alpha Centauri is close, but not all that big either. They are in the southern sky; you cannot see them from North America or Europe.


How close is the nearest star from the sun?

The nearest star(s) to our sun are the Alpha Centauri group. One small star is orbiting one big star. When the large star is in front of the small star (from our view on earth) the big star, Alpha Centauri, is closest. When the small star swings in front of the big star, the small star (Beta Centauri) is closest

What is the closest star to our planet?

The Sun is the closest star but the next one is called Proxima Centauri, about 4 light years away but so dim it needs a really big telescope to see it. Then there is a bright star called Alpha Centauri a bit further away.


Can the human race live somewhere else in the mikyway?

Yes it IS possible.There are over 200 billion stars to choose from. There must be a suitable planet orbiting one of those stars.The BIG problem is getting to them.Our nearest star system, Alpha Centauri is 4.2 light years away. (Unfortunately, to date no planets have been found around them).Our fastest craft, Voyager 2 is travelling at about 35,000 mph. If it was to make it to Alpha Centauri, it would take ..... about 80,500 years!!!


How big is Proxima Centauri?

Pretty small, for a star. Its diameter is about 15% that of the Sun.


Are the star's in a constellation really close together?

In most cases the stars in any given constellation are completely unconnected. They are merely in the same direction in the sky as seen from Earth. They are made up of dim nearby stars and bright far away stars. Take the constellation Centaurus in the southern hemisphere for example. The brightest star in the constellation Alpha Centauri which is in fact 2 stars of the 3 that make up the Alpha Centauri star system. It is the closest Proxima Centauri is only 4.2 light years away and Alpha Centauri A & B only 4.3 light years. The next brightest star Beta Centauri a binary star system is 525 light years away. The next Gamma Centauri a binary system some 130 light years. The only constellation in which many of the stars are associated is the northern constellation Ursa Major. The famous asterism within the constellation is the "Big Dipper" or the "Plough". 5 of the stars make up part of what is known as the Ursa Major Moving Group. This is a number of stars that are roughly the same distance from Earth (about 80 light years) and also seem to be moving in the same direction through space.


Why dosent Alpha Centauri look as big as the Sun?

It would if it was 93 million miles from us. But it's not, it's 4.3 light years away, so it is dimmer. Imagine putting a torch right up next to your eye - now what is brighter, the Sun or the torch? Now move the torch a 100 metres away. What do you see? It's dimmer or less bright. It's the same with stars.

What characteristic do stars in a constellation or asterism share?

There is normally no similarity between stars in a constellation or asterism other than the direction they are in relation to Earth. They are normally a collection of dimmer near by stars and brighter further away stars.An example of this is the constellation Centaurus. AlphaCentauri is the closest star system to earth. It has 3 stars, Proxima Centauri which is about 4.2 light years and Alpha Centauri A and B that are 4.3 light years away.On the other side Beta Centauri or Hadar is a bright star 350 light years away.There are however examples where some or most of the stars are connected.Take the asterism the big dipper or plough in the constellation Ursa Major. Merek (Beta Ursae Majoris), Phecda (Gamma Ursae Majoris), Megrez (Delta Ursae Majoris), Alioth (Epsilon Ursae Majoris) and Mizar (Zeta Ursae Majoris) all seem to be about the same distance from Earth (between 78 and 84 light years) and all seem to be moving in the same direction. They are known as the Ursa Major Moving Group.Only Dubhe (Alpha Ursae Majoris) and Alkaid (Eta Ursae Majoris) do not seem to be connected.
