How much time will it take to reach new-found solar system?
NASA announced the discovery of solar system 'TRAPPIST-1' which is about 40 light-years away and home to seven Earth-like planets. One light-year is a unit of length equivalent to the distance light travels in one year, equating to 9.461 lakh crore kilometres. Hence, it would take 40 years travelling at the speed of light (3 lakh km/sec) to reach there.
