How many Trappist-1 planets are in the habitable zone?

The TRAPPIST-1 system contains a total of seven known Earth-sized planets. Three of them — TRAPPIST-1e, f and g — are located in the habitable zone of the star (shown in green in this artist's impression), where temperatures are just right for liquid water to exist on the surface.

What new planet has been discovered?

The large planet in the foreground is the newly discovered GJ 581g, which has a 37-day orbit right in the middle of the star's habitable zone and is only three to four times the mass of Earth, with a diameter 1.2 to 1.4 times that of Earth.

How was Trappist-1 discovered?

The star we today call TRAPPIST-1 was first discovered in 1999 by astronomer John Gizis and colleagues. At that time, the ultra-cool dwarf star got the unwieldy name 2MASS J23062928-0502285, because it was spotted with the Two Micron All-Sky Survey (2MASS).

What are the names of the planets in Trappist-1?

How long would it take to travel to Trappist-1?

Thus, the TRAPPIST-1 star system is roughly 235 trillion miles away. Traveling at the speed of light, it would take approximately 40 years to reach TRAPPIST-1...which, in cosmic terms, is a neighborly jaunt.

What planet could we live on?

Out of all the planets in our solar system, only Earth is know to sustain life. However, after scientists have analyzed others, some are showing the potential to sustain life, but perhaps in a way we have not seen before. The most likely planets to sustain life include Mars, Europa, Enceladus and Titan.
