KELT 9B - Hottest Gas Giant

NASA has discovered beyond our solar system there are plenty of other solar systems having variety of planets revolving around stars. Scientists have discovered a planet which they call, KELT-9b. This planet is hotter than most known planets in our galaxy. The day time temperature of this planet is more than 7,800 degrees Fahrenheit, yet the star that this planet revolves around is even hotter and the star vaporize the planet during revolution.

This planet is 2.8 times more massive than the giant planet of our solar system, Jupiter, yet less dense. The planet’s atmosphere is made more winded by its star’s enormous magnetic field. KELT- 9b is locked to its star like the moon to the Earth, hence only one side always faces the star where it’s always day and the other side remains throughout in darkness.

Water, methane or carbon dioxide cannot be formed on the day-side of the planet due to extreme temperature, yet the darker side, which is always away from the star, may have properties that support formation of such elements.
The star of KELT-9b is named “KELT-9”. It is younger for scientists claim it to be only three hundred million years old. It is much hotter and larger in radius as compared to our sun. The increased level of ultraviolet radiation may be causing the planet to shed its planetary material like a tail of a comet.

The planet revolves around its star in an unusual manner as compared to planets of our solar system that revolve in an elliptical orbit around the sun. KELT-9b revolves around KELT-9 perpendicular to its axis of spinning. Due to this type of orbit, it takes less than two days for this planet to complete its one year.

The surface of the planet KELT-9b is not habitable, yet scientists like Gaudi deem it important to study the unlivable planets. NASA is trying to study KELT-9b through Spitzer telescope and James Webb Space Telescope which will launch in 2018. Though this planet was first discovered using KELT (Kilodegree Extremely Little Telescope), yet scientists aim to study this planet further using much more advanced telescopes in order to learn more about the self-vaporizing planets.
