PLANETARY LINEUP Seven Earth - sized
planets orbit the star TRAPPIST - 1 with short periods, from 1.5 to 20 Earth days.
The discovery, reported Wednesday in the journal Nature, puts
the planets orbiting the star TRAPPIST - 1 at the top of astronomers» list of places to look for life beyond the solar system.
Not exact matches
TRAPPIST - 1, which is 39 light - years distant and just 8 % the mass of the sun, caught the team's attention because it was obvious from multiple dips that more than one
planet orbited the
star.
Potential targets include
planets orbiting TRAPPIST - 1, a red dwarf
star just 40 light years away.
In May 2016, members of the Belgian
TRAPPIST team announced their small telescope had turned up three potentially habitable
planets orbiting a
star just 40 light - years away.

planets orbiting the nearby dwarf
star TRAPPIST - 1.

planets orbiting the ultracool dwarf
star TRAPPIST - 1, 40 light - years away [1].
Carone and her team considered some of the nearest exoplanets that have the potential to be Earth - like: Proxima b, which is
orbiting the
star nearest to the Sun (Proxima Centauri), and the most promising of the
TRAPPIST - 1 family of
planets,
TRAPPIST - 1d.
Ultimately, this means that while M - dwarf
stars, like
TRAPPIST - 1, are the most common
stars in the universe (and while it's likely that there are
planets orbiting these
stars), the huge amount of water they are likely to have makes them unfavorable for life to exist, especially enough life to create a detectable signal in the atmosphere that can be observed.
Earlier this year, scientists discovered a nearby ultracool dwarf
star (which is regrettably a reference to its temperature rather than its rad style) named
TRAPPIST - 1 with a record - setting seven Earth - sized
planets in its
orbit.
A few of the
planets orbiting a
star called
TRAPPIST - 1, which is 40 light years away, have shown another sign they might be right for life: water.
TRAPPIST - 1e, f, and g, however, represent the holy grail for
planet - hunting astronomers, as they
orbit in the
star's habitable zone [6].
Astronomers using the
TRAPPIST - South telescope at ESO's La Silla Observatory, the Very Large Telescope (VLT) at Paranal and the NASA Spitzer Space Telescope, as well as other telescopes around the world [1], have now confirmed the existence of at least seven small
planets orbiting the cool red dwarf
star TRAPPIST - 1 [2].
A FEW
planets orbiting a
star 40 light years away called
TRAPPIST - 1 have shown new signs they might be right for life: a water - friendly locale.
When astronomers announced the discovery of seven Earth - sized
planets orbiting the ultracool dwarf
star TRAPPIST - 1, Earthlings immediately celebrated the possibility that one of those planetary neighbors could host life.
NASA just announced 7 rocky
planets around the cool red
star Trappist - 1 — and 3 of those
orbit within the Habitable Zone (where surface liquid water would be possible).
A new study has found that the seven
planets orbiting the nearby ultra-cool dwarf
star TRAPPIST - 1 are all made mostly of rock, and some could potentially hold more water than Earth.
From the moment that seven Earth - sized
planets were discovered in
orbit around
TRAPPIST - 1 — an ultracool dwarf
star located 39 light years away — astronomers have been busy trying to learn everything they can about this intriguing
star system, particularly its potential to foster life.
The dwarf
star TRAPPIST - 1 is 1,000 times dimmer than our sun, and is known to host seven closely
orbiting planets.
Because the
planets are in such close
orbits around
TRAPPIST - 1, some or all of them may be tidally locked, which means that they always present the same side to the
star and the opposite side away from the
star.
The
TRAPPIST - 1
star is classified as an ultra-cool dwarf, and these
planets orbit extremely closely.
The
TRAPPIST - 1 system consists of seven Earth - sized
planets orbiting a red dwarf
star.
I missed posting this before, but there are some very interesting updates about the
TRAPPIST - 1 exoplanets (seven Earth - sized
planets orbiting a red dwarf
star 40 light - years away).
Learn about the discovery in 2017 of seven Earth - sized
planets orbiting TRAPPIST - 1, an ultra-cool dwarf
star 40 light - years away.
Learn about the discovery in 2017 of seven Earth - sized
planets orbiting TRAPPIST - 1, an ultra-cool dwarf

This cramped little system finds each
planet's
orbit closer to their
star,
TRAPPIST - 1, than Mercury is to ours.
The team was able to deduce the number of exoplanets, as well as certain characteristics of these alien worlds such as their size,
orbit, and composition, by identifying dips in the perceived light output of
TRAPPIST - 1 as the
planets passed between Earth and the
star, blocking a portion of its light.
TRAPPIST - 1 is an ultra-cool dwarf
star in the constellation Aquarius, and its
planets orbit very close to it.
The best example so far is the
TRAPPIST - 1 system about 40 light - years away, where seven roughly Earth - sized
planets orbit a small, red
star.
