Alpha Centauri, the nearest star, is just over 4 light years away. Traveling at a speed of 2000 miles per hour (the speed of a fast jet airplane), how long would it take to get there in years?

Its visual magnitude is about 11.0

Next nearest star is proxima century 4 .3. light years away. Sun is one A U away from Earth.149597870 KM.

For your long-term-memory: If $alpha$ radian is the parsec angle, the formula for distance = 1/$alpha$ AU. Here, $alpha$=(0.379/3600)($pi$/180) radian.=1.8374 E-06 radian. So, d=1/1.8374 AU=544000 AU. Unit conversions: In lu...

Alpha Centauri is the nearest star as far as present knowledge allows. So the distance to Alpha Centauri is 25700 000 000 000 Putting this value into scientific notation involves...

$1ly~~5.8786*10^12mi$ Therefore, $4.3ly~~4.3(5.8786*10^12)=2.5278*10^13mi$

Alpha centauri .is the star in the constellation of Centaurus..It is 4.37 light years away from Earth.

Light year is the distance traveled by light in one year. Light travels in vacuum 300,000 kilometers per second.

Lighttravels 300000 kilometers inone second

The average speed is $(4.12 E+16)/(1.73 E+10)$ meter/s =2.38 E+03 km/s. The distance of Alpha Centauri is about 4.3 light years= 2.7 E+05 AU = 4.05 E+13 km. The time...
