What else can I help you with?
When we look up at the sky at proxima centauri how old is that light?
That light is 4.2 years old.
How old would you be after sending and receiving a message from Proxima Centauri?
It depends on how old you are to start. Since Proxima Centauri is 4.2 light years away, it would take 8.4 years to send a message an receive a reply.
Suppose you viewed the promixa centouri which is 4.3 light-years from earth how old are you?
Impossible to determine. At least old enough to operate a good telescope, because Proxima Centauri isn't visible to the naked eye.
What is the position of the star proxima centauri?
Proxima Centauri is located in the constellation of Centaurus. It is the closest known star to the Sun, at a distance of about 4.24 light-years. Its coordinates in the sky are RA 14h 29m 47s, Dec -62° 40' 46".
Light takes about 8 minutes to reach the earth from the sun true or false?
True. Light from the sun takes approximately 8 minutes to travel to Earth at the speed of light.
Compare Alpha Centari to the sun?
Alpha Centari is the nearest star to the Solar System's Sun. Alpha Centari is thought to be in the order of at least 4 to 7 billion years old. The Sun's age is estimated to be at the low end 4.6, and thus likely to be much younger. Another difference is that Alpha Centari is really a binary star system, while the Sun is the only star in the Solar System.
How old is Alpha Centauri compared to the Sun?
Alpha Centuari is a star 4.4 light years away. Which is about 44 trillion km (44,000,000,000,000 km) or 44,000 Billion km. Its actually more like 42,479,700,000,000 km if you were exact.
How far is in miles the furthest star?
It is impossible to know how far the furthest star is, since it can't be seen. The universe is said to be aprox 13.8 billion years old, it would be logical to assume that is how far it is in light years. 13.8 billion light years x 5.88 trillion miles per light years is pretty far. The sun is the closest star at 93 million miles. The next closest is, Proxima centauri which is 4.24 light years or 24.925 trillion miles away.
How old is the alpha centauri star?
About 4 850 000 000 years
What is the next nearest star to the planet earth?
Aludra, in Canis Majoris, has a visual magnitude of 2.4 and is 3,200 light years away. On an exceptionally clear, dark night people with good vision can see stars as faint as magnitude 6.5. Most of the stars we can see are within just a few hundred light years of earth. The Andromeda Galaxy contains more stars than our galaxy, and is barely visible as a faint smudge of light below the constellation of Casseopia. All the stars in it are 2.5 million light years away from us. People have reported being able to see the Sombrero Galaxy, a collection of stars 10 million light years away. Most galaxies are so far away we cannot see them with the naked eye. These vast collections of stars may be up to billions of light years away--possibly beyond any visible edge of our universe. We estimate the furthest stars to be some 46 billion light years from us. The reason they remain visible in a universe only 13.8 billion years old is due to the subsequent expansion of space.
When will alpha centauri b die?
Science is unable to know for sure if there is life on the planets surrounding Alpha Centauri. However, it has been identified as one of the environments likely most similar to earth's environment.
