Astrophysicists of the University of Bern have speculated the evolution of a planet stated Planet 9 that is approximately 3.7 times the radius of Earth. The putative planet is located along the outer solar system and has an average temperature of minus 226 degree Celsius. The scientists are the experts in modeling the evolution of planets have been studying the development of exoplanets for years now.
A recent study and the evolution modeling of the putative planet in the outer solar system have raised a few questions. How big is exactly the planet that we are talking about here? What could be the surface like and the exact average temperature? The scientists have been using the James Webb Space Telescope for the purpose of direct imaging of the distant objects that are light years away.
According to the statement by Esther Linder, a PhD Student in the University of Bern, “For me candidate Planet 9 is a close object, although it is about 700 times further away as the distance between the Earth and the Sun.” Planet 9 possibly could be a smaller version of the giants Neptune and Uranus. The land might be completely covered with Ice and the atmosphere constitutes of Hydrogen and helium.
A paper was submitted by Christoph Mordasini, a professor at the University of Bern and a PhD student under him, Esther Linder. The paper has been accepted by the Journal of Astronomy and Astrophysics. The paper projects that the approximate mass of Planet 9 is 10 times that of Earth along with 3.7 times the radius. The average temperature is about minus 226 degrees or 47 Kelvin.
The paper states, “This means that the planet’s emission is dominated by the cooling of its core, otherwise the temperature would only be 10 Kelvin, its intrinsic power is about 1000 times bigger than its absorbed power. With our study candidate Planet 9 is now more than a simple point mass, it takes shape having physical properties.”
