On this scale the distance to Alpha Centauri is 136 kilometers 8 miles. Proxima Centauri is slightly closer at 425 light years.

That is more than 256 trillion miles or approximately 266000 astronomical units or AUs.

. The fastest spacecraft so far launched into space the NASA-Germany Helios probes traveled at 250000 kilometers per hour. New Horizons travels at 36373 miles per hour. The distance in AU d is.

From the question we get information. D 4131013km 15108km1AU. They are about 435 light-years from Earth according to NASA.

The Alpha Centauri system is estimated to be at a distance of roughly 44 light-years from our solar system. Alpha Centauri is a binary star system that is 437 light years away. Alpha Centauri A B are roughly 435 light years away from us.

Its estimated mass is at least 117 times that of the Earth. How far away is Alpha Centauri in kilometers. Suppose this time its the Earth that is the size of a period on a printed page which is by the way about 05 mm.

So the distance to Alpha Centauri is 25700 000 000 000. At 946089 x 1012 km per light year that multiplies out to. According to us the distance to Alpha Centauri is about 4 light years.

Edited by Achernar 09 December 2016 - 0526 PM. Thats the distance between us and Alpha Centauri. At that speed it would take the probes 18000 years to reach the nearest star to the sun.

Now change the perspective again. The current closest star to our Sun is Proxima Centauri from the Alpha Centauri triple star system. The nearest star is Alpha Centauri at a distance of 43 light-years from Earth.

A Triple Star System about 4 Light Years from Earth NASA. Alpha Centuari is a star 44 light years away. It lies 85 light-minutes away from Earth which translates to 149 million kilometers 93 million miles.

On that scale the Sun would be a little smaller than a tennis ball at a distance of some 59 meters 19 feet. A new study involving long-term monitoring of Alpha Centauri by NASAs Chandra X-ray Observatory indicates that any planets orbiting the two brightest stars are likely not being pummeled by large amounts of X-ray radiation from their host stars. 2 pts Yellow light from Alpha Centauri the nearest star system to Earth besides our own Sun takes a whopping 44 years to travel to Earth.

The closest star to Earth other than the sun is Alpha Centauri at some 44 light-years away. Then multiply by the speed of light per hour. Which is about 44trillion km 44000000000000 km or 44000 Billion km.

Light takes slightly longer than 8 minutes to reach Earth from its sun but the light from Alpha Centauri takes over four. Alpha Centauri is the nearest star as far as present knowledge allows. A light-year is the distance that light travels in one year 365 days.

18000 yearsAlpha Centauri is 44 light-years away or nearly 40 trillion kilometers. One AU is equal to the average distance of Earth to its own sun. Proxima Centauri is therefore some 265000 AU.

The average distance between Earth and Sun ae. Scaling the Earth-sun distance at one inch places this star at 44 miles 7 km distant. Thought question not for credit.

The third star is called Proxima Centauri or Alpha Centauri C and it is about 425 light-years from Earth making it the closest star other than the sun. Putting this value into scientific notation involves moving the decimal next to the last digit to the left 2 and multiplying by a power of ten that makes the numbers equal. Going away from her faster than 99c but slow than c A spaceship is headed toward Alpha Centauri at 0999c.

Thats the fraction of lightspeed you want. Each light year is 59 trillion miles or 9 trillion kilometers. This may not sound like a large difference but it means that Proxima Centauri is 620 billion miles closer than Centauri A and Centauri B.

This distance between neighboring stars is how many times larger than the. Is a distance of 93000000 miles or 150000000 kilometers. Its actually more like 42479700000000 km if.

A light year is the distance light travels in one year - it is equal to 9461 x 10 12 km. When we talk about the distances to the stars we no longer use the AU or Astronomical Unit. 1AU 15 108 km.

It is a small and a dim red dwarf star from the constellation Centaurus and is about 4243 Lightyears or 4014 trillion kilometres away from the Sun. Proxima Centauri b or Alpha Centauri Cb orbits the star at a distance of roughly 005 AU 75 million km with an orbital period of approximately 112 Earth days. Take the distance to Alpha Centauri - 436 light years - and divide by 100 years.

Since light moves at 299792458 ms by definition Ill let you work out kmh. Alpha Centauri Courtesy SkatebikerWikimedia CommonsCC BY 30. Commonly the light year is used.

The two main stars are Alpha Centauri A and Alpha Centauri B which form a binary pair. The star Proxima Centauri is about 4014 Trillion kilometres away from the Sun. The distance of the nearest star system Alpha Centauri d 4131013km.

From us and the main pair another 10000 AU. What about the New Horizons spacecraft the first spacecraft ever to visit Pluto and its moons.
