How old is Alpha Centauri compared to the Sun?

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

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.

Answer 6

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.

Answer 7

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.

Answer 8

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.

Answer 9

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.

Answer 10

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.
