MIT researchers discovered a distant planet that orbits 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 the Sun. The planet revolves around the Star at a speed of 81 kilometers per second. The mass of the planet is not yet determined.
Scientists suspect that the planet pi is terrestrial similar to Earth. The planet’s orbit is tight hence the planet is close enough to the star. The star heats the surface of the planet up to 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 nearby, ultra-cool dwarfs. The ultra-cool dwarfs are a stellar 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.
These dwarf planets have low mass and small size, so these planets can handle a relative population of the earth rather than super-earth and Jupiter Massed planets. Due to the slow hydrogen fusion compared to other low mass stars the life span of the planet is estimated to few trillion years. The researchers say the James Webb Space Telescope (JWSB) can be used to see the details of the planet’s atmosphere. James Web Space Telescope will be able to see what Universe looked liked around 100 million years back, we could possibly see when the first star and galaxies started to form.
