If you could drive your car at a steady 100 km how long would it take you to reach the nearest star?

Answer 1

AlphaCentauri is approx. 4.37 C from Earth.

4.1343392 x 10*13 Total km. from Earth.

Travelling at 120 mph ( 193.1213 km. ph. ) it would take approx.

214,079,910,000 ( 2.1407991 x 10*11 ) hrs. OR

8,919,996,250 days OR

24,421,618.75 years

Answer 2

Here is a ball-park, order-of-magnitude answer:

The Alpha Centauri set of stars is about 4.4 light-years from Earth. That means the trip takes 4.4 years at the speed of light.

100 years is (100/4.4) times as long as 4.4 years. If you're giving yourself (100/4.4) times as long to make the trip, then you only have to move (4.4/100) times the speed of light.

Speed of light = 186,282 miles per second.

Required speed = (4.4/100) x (186,282) = 8,196 miles per second = only 29,507,069 miles per hour.

Answer 3

Assuming 100 kph.

Driving to our Sun (which is the nearest star) would take around 171 years, not including rest or fuel stops.

To drive to the next nearest star - Proxima Centauri would take over 45 million years!!

Answer 4

Spacecraft never travel in a straight-line path. But just to get an idea of the kind of distance

this question is talking about, let's assume that one could.

The nearest star to earth is the sun, at an average distance of roughly 157.5 million Km.

Traveling at 100 Km per hour, it would take about 180 years to cover that distance.

The next nearest star to us is Proxima Centauri, at a distance of roughly 4.4 light years,

or about 9,460 billion Km.

Traveling at 100 Km per hour, it would take about 10.8 million years to cover that distance.

Answer 5

Alpha Centauri is 4.4 light years away. To get there in 100 years you would have to travel at 4.4% the speed of light, about 30 million miles per hour.
