Indian scientists have discovered a planet larger than Jupiter 725 light-years from Earth. The discovery was made by researchers at the Physical Research Laboratory in Ahmedabad. The planet orbits a star about one and a half times the size of the Sun. Planets located outside the Solar System are commonly referred to as exoplanets. The now discovered planet is also an extraterrestrial.
Scientists have been able to find the extraterrestrial using a 1.2-meter-long telescope's spectroscopy of Paras in the Physical Research Laboratory. The telescope is located at the Mount Abu Observatory in Rajasthan. Although Jupiter is about one and a half times its size, it is only 70 percent the mass of the discovered planet.
The research was conducted from December 2020 to March this year. More excellent spectrograph information was also obtained from Germany. The new planet is named TOI 1789. The orbiting star is called HD 82139. The research was led by Prof. Abhijit Chakraborty, a scientist at the Physical Research Laboratory. His team included various researchers from the US and Europe.
You know that it takes 365 days for our earth to orbit the sun once. But it takes the planet just 3.2 days to orbit the star. This is because the planet is located very close to the star. Very few stellar-planetary systems have been found so close together. Due to its proximity to the star, the planet's surface temperature is very high. This causes temperatures on the planet's surface to reach 2000 kV. The density is also low. This is the second extraterrestrial being discovered by the Physical Research Laboratory using a paras spectrograph. K2–236B was the first planet to be found 600 light-years away. This was in 2018.
