Three or four planets – e, f, and g or d, e, and f – are located inside the habitable zone. As of 2017, this is the largest known number of planets within the habitable zone of a star or star system.

Does TRAPPIST-1 have planets?
The seven Earth-size planets of TRAPPIST-1 are all mostly made of rock, with some having the potential to hold more water than Earth, according to a new study published in the journal Astronomy and Astrophysics.
How many planets are in the TRAPPIST-1 system?
7 planets The 7 planets of the TRAPPIST-1 system orbit their star at a distance that would easily fit within the orbit of our solar system's innermost planet, Mercury. Planets e, f and g are located within TRAPPIST-1's habitable zone. Image via NASA/JPL.
What solar system is TRAPPIST-1d in?
TRAPPIST-1 system TRAPPIST-1d is one of seven Earth-sized planets in the TRAPPIST-1 system.
How are some of the planets in the TRAPPIST-1 system similar to Earth?
A new study published today in the Planetary Science Journal shows that the TRAPPIST-1 planets have remarkably similar densities. That could mean they all contain about the same ratio of materials thought to compose most rocky planets, like iron, oxygen, magnesium, and silicon.
What is the name of 9 planets?
The order of the planets in the solar system from nearest the sun are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.
Is TRAPPIST-1 a flare star?
TRAPPIST-1 is an active star with frequent flaring, with implications for the habitability of its planets. Superflares (stellar flares whose energy exceeds 10^33 erg) can completely destroy the atmospheres of a cool star's planets, allowing ultraviolet radiation and high-energy particles to bombard their surfaces.
How much longer can we survive on Earth?
Humanity has a 95% probability of being extinct in 7,800,000 years, according to J. Richard Gott's formulation of the controversial Doomsday argument, which argues that we have probably already lived through half the duration of human history.
Is there life on TRAPPIST-1e?
Furthermore, according to the Habitable Exoplanets Catalog, TRAPPIST-1e is one of the most potentially habitable exoplanets discovered….TRAPPIST-1e.
