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".
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.
How many light years from the earth is the sun?
The sun is not light years away but light minutes and the sun is 8 (rounded) light minutes away from us. But if you really want to know how far away the sun is from us in light years it is 0.000015 of a light year away from us.
If you are 11 years old now how old will you be when light that is leaving today reaches earth?
One light-year is about 9 trillion kilometers.Arcturus is a star that is 37 light-years from Earth.
Why is looking in a telescope like looking back through time?
The light from our own sun takes roughly 8 minutes to travel the distance to us. That means when you look up at the sun (don't do that without special glasses) you are looking at the sun as it was 8 minutes earlier. Or you can say you are seeing the sun 8 minutes back in time. The stars which are far away galaxies, the light takes years to reach us. So the light we see at night now can be 100 years old. Or we are seeing that galaxy as it was 100s of years ago.
How old were you when the light that you see left Proxima Centauri?
I was 64.
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.
How fast light travels in night?
Light is a type of energy, and it moves very fast! It moves so quickly that when you turn on a light switch, you can't even tell that the light from a lamp or light bulb has to travel to fill up a room.It does travel though. Just like an ocean wave, it takes time for the energy to get from one place to another. In the case of light, it travels over 186,000 miles in a second! That number of miles is a bit large to even imagine, but that means the energy of light could loop around the Earth seven times in about as long as it takes you to say, "Mississippi."Seeing back in timeEven though light travels super fast, it can still take light awhile to get from certain far away places to our eyes. Some of the farthest-away objects that we can see with our eyes are the stars!The next closest star to Earth after the Sun is Proxima Centauri. It's so far away that light takes about 4.2 years to get from the star to our eyes! That means that the light we're seeing is 4.2 years old! We see what the star looked like 4.2 years ago, so if a big change happened there today, we wouldn't know for 4.2 years, when the light reaches us!Imagine if someone looked at you today and saw what you looked like 4.2 years ago. How old were you then? How much have you changed? When we look at the night sky, we're seeing very old light. It's like looking back in time!
