How long would it take to travel to Kepler 22b?

Answer 1

Comets follow very long trajectories through the solar system. When they are close to the Sun and easily visible, the are generally under 15 light-minutes away. (The Sun, by comparison, 8.3 light-minutes away.) When a comet is out beyond the orbit of Neptune, it could easily be 50 or more light-HOURS away, and possibly more than 2 light-WEEKS. The outer boundary of the hypothetical "Oort Cloud" is between 4-10 light-MONTHS.

Answer 2

Kepler-22 is located about 600 light years from us.

At a constant light speed, it would take 600 years, however in reality with acceleration and deceleration it would take a lot longer.

Also, being 600 light years away, we are seeing it, as it was 600 years ago, so it may not be there when we arrive. However, the chances are good, as it is a star similar to our own Sun.

Answer 3

According to Wikipedia, the distance to Betelgeuse is estimated at 643 ± 146 light-years. That means it will take that many years (somewhere between 500 and 800 years, depending on the exact distance) to travel there at the speed of light.

Answer 4

Betelgeuse is approximately 430 light years away, or a bit over 3.7 million light hours.

Answer 5

Its between 500 to 790 light years away, but it has been proven difficult to measure. 644 light years is the approximation.

Answer 6

Roughly 387,697,079.34866893 years. With current space technology.

Answer 7

About 640 years.
