Astronomers have discovered the hottest planet of the universe first time. They named this planet as WASP-33b and called the gaseous surface as HD15082 which has a temperature of 3200C. This planet is at a distance of 380 light-years from our earth and is in the constellation of Andromeda.
In fact, the astronomers were first alerted to WASP-33b’s existence in 2006, after observing regularly timed dimmings of its parent star. This was caused by the planet, four and a half times the size of Jupiter, orbiting its star at less than 7 percent the distance of Mercury from the sun.
A study led by Alexis Smith of Keele University in Staffordshire, and reported in ‘New Scientist’, discovered WASP-33b’s thermal emission using an infrared camera on the William Herschel Telescope in the Canary Islands.
WASP-33b completes an orbit every 29.5 hours. Its temperature is 900C hotter than what was formerly the hottest known planet in the Milky Way Galaxy WASP-12b.
The WASP-12b is so close to its sun-like star that it is superheated to 2,300C and stretched into a football shape by enormous tidal forces. It completes an orbit every 1.1days.
The atmosphere has ballooned to nearly three times Jupiter’s radius and is spilling material onto the star. The planet is 40 percent larger than Jupiter.
