What star is closest to your solar system?
Proxima Centauri, roughly 4.243 light years from our Solar System. Its a Red dwarf and is part of Alpha Centauri system which includes 3 stars. Alpha Centauri A and Alpha Centauri B are about 4.37 light years away. and the planet Eris is red it is about 3 billion miles away from the Sun and it is 1 billion miles away from our Earth.Proxima Centauri4.2421 light years away
What is the distance of proxima centauri to the earth?
Approximately 40.1 trillion kilometres. The distance of Proxima from here is 4.24 light-years. A (Julian) year is 3.15576 × 107 seconds, and the speed of light in vacuo is 2.997 924 58 × 108 metres per second. That makes a light-year 9.461 × 1015 metres. 4.24 times 9.461 × 1015 metres is 4.011 × 1016 metres, which is 4.011 × 1013 kilometres. Round to the number of significant figures in the least precise factor.
What does par in parsec means?
parallax[parallax+second], in astronomy, basic unit of length for measuring interstellar and intergalactic distances, equal to 206,265 times the distance from the earth to the sun, 3.26 light-years, or 3.08×1013 km (about 19 million million mi). The distance in parsecs of an object from the earth is the reciprocal of the http://www.answers.com/topic/parallax of the object. The nearest star, Proxima Centauri, has a parallax of 0.763″ of arc and a distance of about 1.31 parsecs.definition from Answers.com
How long will it take you to reach Alpha Centauri 4.37 light years away if you are travelling 16000 mph?
As the distance to Alpha Centauri is 4.367 light years then traveling at the speed of light it would take 4.367 years to get there. However due to the effects of special relativity the travelers would experience the trip as instantaneous (i.e. taking no time at all). From the earth if the travelers sent back a message as soon as they arrived, that message would arrive 8.734 years after the travelers departed.
Why stars distances are measured in light years?
A light-year provides a readily convertible distance that is large enough that vast stellar distances can be expressed in smaller, easily compared numbers. For example, distances to "nearby" stars are from 4 to about 25 light-years, while a galaxy's diameter may be 100,000 light-years or more, and the distances between galaxies are in the millions and billions of light-years.Using kilometers would require larger named numbers or exponents, which could be less clear. Each light-year is about 1.2 trillion kilometers or about 978 billion miles.For shorter distances, a useful unit is the AU, or Astronomical Unit. This is the average distance between the Earth and the Sun, about 93 million miles. If we were measuring or comparing the distances of planets from the sun, they would be expressed in AU's and not light-years. For further distances the light-year is used. It is easier to say 4.2 light-years to Proxima Centauri than 4,125,987,200,000 miles.Another even larger unit, the parsec (parallax second), is based on astronomical angular measurement and is equal to about 3.26 light-years.

Which star is the second nearest star to the earth?
Proxima Centauri at about 4.2 light years.
How far is the sun from proxima centauri in light minutes?
Proxima Centauri is 4.243 light years away, or 2,231,648 light minutes.
Proxima century and alpha century?
Proxima Centauri (note spelling) and Alpha Centauri are stars in a trinary some 4.3 light years from earth (at the present time).
What star is closest to the earth other than the sun?
Alpha Centauri, which is 4.2 light years away from the Earth.
Which is the closest star to earth not counting the sun?
The closest star to earth is the sun. The next closest is a red dwarf star called Proxima Centauri, much further away. The sun is around 8 minutes away at the speed of light, while Proxima Centauri is around 4.2 years away at the speed of light (light years).
What is the closest star to earth excluding your sun?
Proxima Centauri . . . . . 4.2 light years away.
How many years pass before light from Alpha Centauri reaches earth?
Alpha Centauri is a triple star system. Alpha Centauri A, B & C or Proxima Centauri. Alpha Centauri A & B are 4.37 light years from the Earth whereas Alpha Centauri C is 4.243 light years.
What is the name of your nearest star except the sun?
Proxima Centauri is closest at 4.3 light-years from the Earth.
What is our star?
If you're counting the Sun that's it. Proxima Centauri is next at 4.3 light-years from the Earth
