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.
Alpha Centauri is a system of three stars. Alpha Centauri A has a temperature of about 9,960 degrees Fahrenheit. Alpha Centauri B has a temperature of about 9,000 degrees. Alpha Cenaturi C, also called Proxima Centauri has a temperature around 5,000 degrees.
Proxima Centauri is a red dwarf star about 4.2 light years from us, in the constellation of Centaurus.
It is believed that the Centauri star system formed about the same time as our own star (The Sun) at 4.85 × 109 years.
This star is at a distance of 4,37 light years from the sun; the sun is at a distance of approx. 150.106 km from the earth. Calculate the time (distance/speed) if you know the speed of your vehicle.
That depends on how fast you travel and what route you take.
Spacecraft never travel in straight lines, but let's say you could do that.
-- At the speed of light in a straight line, it would take 4.4 years
-- Driving 75 miles an hour, it would take 39.3 million years
-- Flying a million miles a minute -- almost 9% of the speed of light -- you'd pass the moon
in 14 seconds, the sun in an hour and a half, and be at Alpha Centauri in only 49 years.
Alpha Centauri is a triple star system.
- Alpha Centauri A is VERY similar to our own Sun, slightly larger and older.
- Alpha Centauri B is similar in size (smaller) but has a lower temperature.
- Alpha Centauri C (Proxima Centauri) is a red dwarf and NOTHING like our Sun.
If you travel at the speed of light, 4.2 years. If you travel at the speed of the fastest space craft that we have now, such as voyager at 35000 mph, then it will take Approximately 134,433.2 years to travel that distance. Pack a lunch. And as per the hitchhikers guide to the galaxy, dont forget your towel.
Alpha Centauri is a binary star system, two stars of similar size and mass to our own sun that are in orbit around each other. Their distance from each other can vary, from around 11.2 Astronomical Units (AU), where one AU is the same as the Earth to sun distance, to around 35.6AU.
11.2 AU is around 1.7 billion km, or approximately the sun to Saturn distance. 35.6 AU is around 5.3 billion km, further than the sun to Neptune distance. They complete one orbit about each other every 80 years.
If we could travel at the speed of light, it would take a little over 4 years to travel to Alpha Centauri. We are not able to travel anywhere NEAR the speed of light, so it will take much longer.
One type of spacecraft that we do know how to build NOW would be an Orion nuclear pulse rocket. Depending on the size and the number and type of nuclear explosives used, an Orion spacecraft might reach 10% or more of the speed of light; this would make the trip to Alpha Centauri in about 50 years. However, none of the Centauri stars are likely to have habitable planets. The star Epsilon Eridani is similar to our Sun, and might possibly have habitable planets. However, none of the exoplanets yet discovered would be habitable, and we do not have any way - currently - to detect planets as small as the Earth.

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.
How old is the star procyon?
Procyon is estimated to be around 1.7 billion years old. It is a relatively young star compared to the sun, which is about 4.6 billion years old.
What is the age of the star vega?
No one knows exactly, but they do know that it's about 1/10 the age of our sun. It's also evolving so quickly that it's almost in the mid point of it's life. It used to be our North Star about 13,000 years ago, and will be again one day....
How old is the sun right now It is a billion years old?
Our sun is about 4.6 billion years old, about halfway through its life.
The largest stars are times the mass of the sun?
The largest star known, Eta Carinae, has about 150 times the Sun's mass but it is only 3 million years old and likely to explode in less than a million years so is unstable and short-lived compared to other stars.
Compare Alpha Centari to the sun?
Alpha Centauri is a triple star system consisting of Alpha Centauri A, B, and Proxima Centauri, with A and B being similar to the Sun in terms of size and temperature. However, Alpha Centauri is slightly larger and brighter than the Sun. Proxima Centauri is a red dwarf star that is much smaller and cooler than the Sun.
How old is the alpha centauri star?
About 4 850 000 000 years
When will alpha centauri b die?
Alpha Centauri B is a star similar to our Sun and is estimated to have a lifespan of around 6-7 billion years. It is currently around 6 billion years old, so it still has several billion years left before it exhausts its nuclear fuel and reaches the end of its life cycle.
How old is the Sun compared to the Universe as a whole?
The Sun is about 4.6 billion years old, while the Universe is estimated to be about 13.8 billion years old. So, the Sun is relatively young compared to the age of the Universe.
How old were you when the light that you see left Proxima Centauri?
I was 64.
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.
When we look up at the sky at proxima centauri how old is that light?
That light is 4.2 years old.
How old is the star procyon?
Procyon is estimated to be around 1.7 billion years old. It is a relatively young star compared to the sun, which is about 4.6 billion 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.
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".
How old is Alpha Condé?
Alpha Condé is 71 years old (birthdate: March 4, 1940).
How old is Alpha Blondy?
"Alpha Blondy" (Seydou Koné) is 64 years old (birthdate: January 1, 1953).
