The planets are located in the Trappist-1, a system with seven worlds orbiting a dwarf star 39 light years away. Since Nasa first announced its discovery of Trappist-1, many have argued life could exist there. Now, scientists believe Earth-like planets d and e are likely to have water and enough heat to harbour life.
Scientists have discovered seven Earth-sized planets orbiting a small star 39 light-years away, with several planets believed to be capable of having water.
Based upon parallax measurements, this system is located at a distance of about 39.3 light-years (12.0 parsecs) from Earth. Both stars are solar analogs that have characteristics similar to those of the Sun. They belong to the Zeta Herculis Moving Group of stars that share a common origin.
The volume of space lying within 20 light-years of Sol encompasses over 33,509 cubic light-years. Within that vast sphere, astronomers have been able to detect at least 50 Solar-masses of visible matter bound up in 138 luminous stars and weakly glowing white and brown dwarfs thus far.
TRAPPIST-1 is 39 light years away. Yes, that is crazy close in the scheme of the universe. The Milky Way galaxy alone is 100,000 light years across.
TRAPPIST-1 is a planetary system, located 12 parsecs away from the Solar system (39 light years), near the ecliptic, within the constellation of Aquarius. Around a star which is 12 times less massive than the Sun and only slightly larger than Jupiter, there are at least seven planets in orbit.
NASA: We found 7 Earth-sized planets just 40 light years away. ... This is the first time that astronomers have discovered another solar system with seven planets roughly the same size as ours ...
A spacecraft that fast could travel 39 light-years in less than 200 years. But that concept has yet to leave the ground. An artist's impression of the view from a planet in the TRAPPIST-1 system.
The new exoplanets have been detected orbiting an ultracool dwarf star called TRAPPIST-1, which is located about 39 light-years away from our Sun in the Aquarius constellation. Astronomers led by Michaël Gillon from the University of Liège in Belgium first detected three exoplanets around the star back in May 2016, using Earth-based telescopes.
Thirty-nine light years isn't that much in the greater scheme of things, but with speeds matching Voyager 1, you'd be looking at around 17,000 years travel time.
