Hottest planet is hotter than some stars


Recommended Posts

Astronomers have found the hottest planet yet, a gas giant with a temperature of nearly 3200 ?C, which is hotter than some stars.

A collaboration called the Super Wide Angle Search for Planets (SuperWASP) announced hints of the planet's existence in 2006. The group had observed periodic dimmings of the parent star possibly caused by a planet about 1.4 times the size of Jupiter passing in front of the star once per orbit.

Follow-up measurements confirmed the planet's presence in 2010, showing distortions of the star's light spectrum that could only be due to a planet's influence. The measurements showed the planet's mass is less than 4.5 times that of Jupiter.

Called WASP-33b, the planet orbits its star at less than 7 per cent of Mercury's distance from the sun, whipping around the star once every 29.5 hours.

A planet (from Greek πλανήτης αστήρ "wandering star") is a celestial body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighbouring region of planetesimals.

Crazy that this ball of gas is that hot, but still considered a planet, and has not burned off the gas or anything.

I don't see how a Sun can be 3200 C, or less. :unsure:

Our sun is supposedly 'millions' of degrees, which I doubt.

The temperature of our sun is 5778 K (surface) and 13.6 million K (core)

The sun heats our planet 93 million or so miles away and you doubt it. So is the sun about 700F maybe 750F then?

^ No, I just don't subscribe to the sun theory of how heat is created.

I believe that much higher frequency radiations are converted to heat, when they strike the Earth's atmosphere. ;)

And you need not bother with trying to tell me otherwise -- it will fall on deaf ears.

So we can walk on the sun with your logic! I love it! *gets in line* :p

Then why do objects without an atmosphere such as the moon register massive temperature swings where the light merely shines upon the surface versus the darkside?

the sun does eminate infra red radiation.

But yeah, the sun is hot....its certainly not cold.

Riiiight

Stick to just posting the articles, seriously...
