What is the position of the star proxima centauri?
You're right about that ! Yes, but just in case anyone is wondering, our Sun is the closest star to Earth.
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.
Light takes about 8 minutes to reach the earth from the sun true or false?
True. The light you see from the sun is 8 minutes old. The nearest star, other than the Sun, Proxima Centauri. The light you see is 4.22 years old!
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?
You're right about that ! Yes, but just in case anyone is wondering, our Sun is the closest star to Earth.
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.
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
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!
