None that are known. There may be a roughly Earth-sized planet in orbit around Alpha Centauri B, but this planet, if it exists, would be far too hot to support life.

What does a person need to see Proxima Centauri?
Proxima Centauri is a red dwarf and the third star of the binary system of Alpha Centauri. You need to be 'below' -600 latitude and have have a telescope capapble of resolving a a star with an Absolute Magnitude of 15.5 or better. Which is a very powerful telescope for any but professional astronomers. It can only be seen from a very few places in the US, and then very poorly as it is too near to the horizon even at its highest.
How far is the nearest habitable planet?
In the near future the Sun will start to grow and Earth will start to die. As the Sun grows the habitable zone will move further outwards. Mars's polar ice caps will start to melt and cover the planet with liquid water as Earth's water evaporates. If we have the technology when this happens we will be able to travel to Mars and live there until the habitable zone leaves Mars. After that happens we will have to live on asteroids and other moons. Almost all the inner planets will incinerate then the Sun will shrink and grow and shrink again until the Sun's core collapses and explodes. So the closest habitable planet will be Mars which is 50 million miles away.
Which is the brighter star Antares or Betelgeuse?
Out of that list, Alpha Centauri is the nearest star to Earth. But there is one closer: Proxima Centauri is a tiny, dim red dwarf star; "near" Alpha Centauri only by astronomical standards, it is still 3 light MONTHS away. But that's still 3 light months closer to the Sun.
Other then sun what other stars are near the earth?
Proxima Centauri Rigil Kentaurus Barnard's Star
If you could travel at the speed of light how long would it take to travel form our solar system to the nearest star?
The nearest star (besides our sun) is 4.24 light-years from earth. This means that light emitted for this star takes 4.24 years to reach earth. Some stars are over millions of light-years away. The closest star is the sun. Beyond that is Proxima Centauri, at 4.24 light-years away. Alpha Centauri is at 4.37 light-years, and beyond that is Barnard's star at 5.97 light-years away. 4.24 light-years = roughly 24,925,000,000,000 miles (rounded to the nearest billion miles) lol
What is the closest star near to the sun?
Alpha Centauri
What stars are near in the earth?
The Sun is the closest star. Next closest are the three stars of the Alpha Centauri system, of which the closest is Proxima Centauri.
How will alpha Centaurus's death affect us?
"Alpha Centauri" is actually THREE stars, not just one. Whenever one of those stars die, we'll probably hardly notice; this will happen in the distant future, and Alpha Centauri will then no longer be anywhere near our Solar System.
How many stars are near mars?
Our sun is the nearest star to Mars. Alpha Centauri is the next nearest at 4 light years.
How old is Alpha Centauri compared to the Sun?
The Heliopause is at a distance of appx 120 AU from the Sun. That is around 0.0019 light years. Te Alpha Centauri star system is 4.365 light years away from the Sun, and almost the same distance away from the Heliopause.
Betelgeuse Alpha Centauri Polaris Antares Which of these stars are closest to the earth?
Every star is pretty huge, compared to anything in our life experience.In size.Betelgeuse: Red giant. Diameter 1,180 solar radii.Aldebaran: Orange giant: 45 solar radii.Alpha Centauri - Which one? A, B or C. For A, yellow dwarf: 1.22 solar radii.Polaris: Which one? A, Ab, B , C or D? For A, bright giant, 46 solar radii.So a simple question can be so difficult. All are giants except Alpha Centauri, however, as this is a homework question, the teacher is obviously looking for Betelgeuse.
How far is earth from the the stars?
The nearest star neighbors to the Earth are three stars that make up a multiple system. To the naked eye the system appears as a single bright star, Alpha Centauri. Alpha Centauri is a double star -- two stars revolving about each other that are too close to be seen as separate by the naked eye. Near them is the third member of the system, a faint star known as Proxima Centauri, our sun's closest neighbor. Proxima Centauri is 4.3 light-years from the Sun (and Earth). It lies at a distance of over 24,000,000,000,000 miles, about 270,000 times farther than the distance between the Earth and the Sun.

How near or far from the sun would make the planet uninhabitable?
The position the Earth is currently and for the past 4 billion years has been the only place this planet can be habitable. If we moved even a mile farther or closer to the sun, we would most likely freeze or burn to death.
If humans had no technology what would the most habitable place on Earth be?
Somewhere near the equator.
