Proxima Centauri is 4.2 light years away, so it would take 4.2 years for light from that star to reach us.

What is the equation for the travel time to the nearest star at the speed of light?

The formula to calculate travel time at the speed of light is distance divided by the speed of light. The nearest star to Earth is Proxima Centauri, which is about 4.24 light-years away. Therefore, the travel time to Proxima Centauri at the speed of light would be 4.24 years.


If you could travel at the speed of light how long would it take to travel form our solar system to the nearest star?

The nearest star (besides our sun) is 4.24 light-years from earth. This means that light emitted for this star takes 4.24 years to reach earth. Some stars are over millions of light-years away. The closest star is the sun. Beyond that is Proxima Centauri, at 4.24 light-years away. Alpha Centauri is at 4.37 light-years, and beyond that is Barnard's star at 5.97 light-years away. 4.24 light-years = roughly 24,925,000,000,000 miles (rounded to the nearest billion miles) lol


How long does it take for a radio transmission to go from earth to alpha centauri and back?

It takes about 4.37 years for a radio transmission to travel from Earth to Alpha Centauri (the nearest star system) and another 4.37 years for the signal to travel back. This means a total round-trip communication time of around 8.74 years.


How long would it take to travel from earth to proxima centauri at a constant speed of1000000 mph?

Light goes at 670 million miles per hour, which is 670 times faster, and it takes 4 years to get to the nearest star. So at one million miles per hour it would take 2700 years to travel there.


Which star is hotter the sun or proxima centauri?

Proxima Centauri is a red dwarf, a common type of star but very dim despite its closeness, and less hot than the Sun at its surface. It is only 4.24 light-years away but only a magnitude 11 star, so a hundred times dimmer than the faintest that can be seen by eye. It is 0.237 light years from Alpha Centauri from where it would be seen as a 5.5 magnitude star, so only just visible.

What two objects are most likely 4 light years apart?

The two objects most likely to be 4 light years apart would be two stars in our closest neighboring star system, Alpha Centauri. This system consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri.


How long from car to get to Proxima Centauri star?

Proxima Centauri, the closest star to Earth, is about 4.24 light-years away, which is roughly 24.9 trillion miles. If you could drive a car at a constant speed of 60 miles per hour, it would take over 4.5 million years to reach Proxima Centauri. This illustrates the vast distances in space, making interstellar travel far beyond our current capabilities.


How long to get to the nearest star other than the sun at 100 mph?

It would take over 114,000 years to reach the nearest star (Proxima Centauri) traveling at 100 mph. This distance is approximately 4.24 light years away, meaning it would take light over four years to travel them.


How long would it take in the space shuttle to get to the closest star?

It would take thousands of years to travel to the closest star, Proxima Centauri, using current space shuttle technology. The distance between Earth and Proxima Centauri is about 4.24 light years, which is equivalent to about 25 trillion miles.
