MIT researchers discovered a distant planet that orbit its star every 3.14 days, similar to the value of “pi” i.e. 3.14. (pi planet)
This new planet is labeled K2-315b, the researchers estimate that the planet has a radius of 0.95 that of Earth’s. The star to which planet orbits is about one-fifth the size of Sun. The planet revolves around the Star at the speed of 81 kilometres per second. The mass of the planet is not yet determined.
Scientist suspect that the planet pi is terrestrial similar to Earth. The planets orbit is tight hence the planet is close enough to the star. The star heats the surface of the planet upto 350o Fahrenheit. As the surface temperature is this high hence planet is not habitable.
The researchers are the members of SPECULOOS (The Search for Habitable Planets Eclipsing Ultra-Cool Stars), the SPECULOOS telescope is designed to search for Earth like planets around nearby, ultra-cool dwarfs. The ultra-cool dwarfs is a stellar of sub-stellar object that has an effective temperature under 2,430o C. These ultra-cool dwarfs are scattered all over the sky. SPECULOOS is a targeted ground based survey, this survey is helpful because these ultra-cool dwarfs can be studied one by one.
The researchers say the James Web Space Telescope (JWSB) can be used to see the details of the planets atmosphere.
