Can a human being ever reach Kepler-452b?

If human beings ruin this planet, the best replacement for Earth might be Kepler-452b. read more

Light from the Sun takes around eight minutes to reach Earth, so naturally, a trip to Kepler 452b would take an incredibly long time. Nasa's New Horizon probe - the one that recently took the amazing pictures of Pluto - left Earth's orbit faster than any other spacecraft before it, at around 36,373 mph. read more

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 travel at the speed of light. read more
