NASA discovered a new solar system with 7 earth like planets
New Solar System : Discovery
- NASA’s Spitzer Space Telescope has discovered a new solar system that could host alien life.
- Using a robotic telescope operated by Liverpool John Moores University, NASA has discovered SEVEN planets which are similar in size to Earth, rocky and probably have ocean.
- The new solar system, with seven rocky, Earth-sized planets, orbiting around a single star.
- The system, which lies around 40 light years (235 trillion miles) from Earth, has been named TRAPPIST-1, after a Chilean telescope that discovered three of the planets in 2016.The Transiting Planets and Planetesimals Small Telescope, hence the name “TRAPPIST” for the system.
New Solar System : Planets
- All seven of the planets of the new solar system lie closer to their star than the closest of our solar system’s planets, Mercury lies to the Sun.
- Scientists believe TRAPPIST-1’s star is cooler than our own.
- In 2018, NASA will launch its new James Webb Telescope in 2018, which is capable of detecting the chemical properties of water, methane, and oxygen in potential atmospheres. So will be helpful to get more information about the system.
- Six of the planets lie in the habitable zone of a cool dwarf-star known as TRAPPIST-1 which is 39 lightyears from Earth.
- The six habitable planets have a surface temperature ranging from 0-100 degree Celsius the temperature region which is perfect for supporting life.
- Of these six, at least three of the planets have an ocean – and scientists state that anywhere on Earth you find water, you are likely to find life, which is why astronomers look for these on other planets.
- NASA said it would take a jet plane 44 million years to reach the new solar system which is 39 light years away or 235 trillion miles.
- The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system.
New Solar System : Structure
- The planets, which have been named alphabetically from b to h, all orbit closer to TRAPPIST-1 than Mercury orbits the Sun.
- The closest planet takes just 1.5 Earth days to complete one orbit, while the farthest planet takes around 20 days to circle the star. Because of this, they’re all a super tight bunch.
- When TRAPPIST-1f and TRAPPIST-1g are at their closest to one another, they’re just at three times the distance between the Earth and the Moon.
