The science journal Nature recently posted their discovery of seven new planets orbiting dwarf star TRAPPIST-1. The article was posted February 23.
The planets, found with NASA’s Spitzer Space Telescope, are being called a new record with seven Earth-like planets orbiting one star. This is because it is the largest number by far in comparison to any other planetary system. NASA’s Spitzer Space Telescope is an instrument used to locate far planets and other astronomical objects. It is the fourth and final of NASA’s series of Great Observatories satellites.
These seven planets revolve around the star TRAPPIST-1 in a tight formation. TRAPPIST-1, being of a similar size to Jupiter, only slightly larger. It is located within the Aquarius constellation about 40 light years from Earth.
The seven planets were shown to have a similar construction to Earth’s size and mass; Three of which are assumed to be habitable.
It is possible these Earth-like planets may have the possibility to contain life. The balanced temperatures indicate the possible existence of water on their surfaces. Some of the planets found have also shown to have satisfactory atmospheric pressure. With the similar masses and sizes to Earth’s, scientists are hoping to succeed in their goals of finding more habitable planets.
