Kepler 452b is 1 400 light years from earth and each light year is 5 88 trillion miles which means it would take the best part of a millenium and a half to reach it if a spacecraft could. According to bennett a spaceship going that fast would take 28 000 years to reach kepler 452b from earth.
At 1 of the speed of light it would take 62 000 years.
How long would it take to get to kepler. Of course voyager 1 isn t going in the right direction. Kepler 186f is about 500 light years away. At the speed of light it would take 620 years.
Ok getting to kepler 452b is no. At warp 9 it travels 1516 38c 1516 38 times the speed of light and would get there in 336 days 23 hours 41 minutes a full year faster than the enterprise a. So at 13km s it would take about 12 million years to get there.
So traveling at light speed it would only take a little more than 4 years to get there. Using a space shuttle it would take 23 4 million years to reach it. If a spacecraft carrying humans travelled at this speed towards kepler 452b it would take the unlucky astronauts around 25 8 million years to get there.
That ould be 1 860 miles per second. The kepler team has spotted 1 094 new candidate planets with 54 candidates in habitable zones and 10 about the size of the earth. An improvement sure but it would be hard to convince people to go on a journey that.
But honestly even if it is there we wouldn t really want to visit as it is amazingly close to its parent. That s about 5×10 15 km 5 million billion km. The planet is being called closest to our earth because of its similarity and size.
How fast can you go.
