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 are the 7 planets?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.
Where are the Trappist planets?
Located about 40 light-years from Earth, TRAPPIST-1 hosts seven rocky planets that are about the size of Earth or smaller — the largest group of roughly Earth-size planets ever found in a single stellar system.
What type of planet is Trappist 1e?
terrestrial planet
TRAPPIST-1e is confirmed to be a terrestrial planet with a solid, rocky surface. It is cool enough for liquid water to pool on the surface, but not too cold for it to freeze like on TRAPPIST-1f, g, and h.
Who discovered the TRAPPIST-1 system?
This video details a system of seven planets orbiting TRAPPIST-1, a discovery of the Spitzer Space Telescope, operated by NASA’s Jet Propulsion Laboratory in Pasadena, California. This animation visualizes the change in light as each planet passes in front of its star.
When was the Trappist system discovered?
2016
The TRAPPIST-1 star system is home to the largest batch of roughly Earth-size planets ever found outside our solar system. Discovered in 2016 some 40 light-years away, these seven rocky siblings offer a glimpse at the tremendous variety of planetary systems that likely fill the universe.
How are planets named?
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. Jupiter, Saturn, Mars, Venus and Mercury were given their names thousands of years ago. Jupiter was the king of the Roman gods, and Saturn was the Roman god of agriculture. Uranus was named after an ancient Greek king of the gods.
