The Hottest Giant Planet Yet: 7800 degrees F.

In summary, the New Scientist article discusses the discovery of a new planet, Kepler-70b, which is the hottest giant planet known to date. It is twice the size of Jupiter and has a surface temperature of 7800 degrees Fahrenheit, making it even hotter than the surface of the Sun. This planet is mainly composed of iron and its high temperature raises questions about its future.

This planet is 7800 degrees F--versus "only" 860 degrees F for the Sun's hottest planet, Venus.

Kepler-70b holds that record, at ~7000 K (12000 F) - hotter than the surface of the Sun.

Edit: Changed thread title, see post 5.

That link souggest iron as the main constituent. However, that surface temperature is way, way above the point at which iron vaporizes. So does that suggest a relatively short future for this planet.

Where is the problem with a gas?
Earth is above the boiling point of nitrogen and it is the main component of the outermost layer.

The density estimates are still discussed, but the planet is certainly very hot.

Apologies. The new planet is the hottest giant planet known; but Kepler 70 b, which is smaller than Earth, is indeed even hotter. So I should have entitled this, "The Hottest Giant Planet Yet: 7800 F."
 

FAQ: The Hottest Giant Planet Yet: 7800 degrees F.

1. What makes this giant planet so hot?

The high temperature of this giant planet is due to its close proximity to its parent star, which causes it to receive a significant amount of radiation and heat.

2. How does this giant planet compare to other known planets?

This giant planet is significantly hotter than any other known planet, including our own solar system's hottest planet, Venus, which has an average temperature of 864 degrees F.

3. What is the composition of this giant planet?

This giant planet is likely composed of gas, similar to other gas giant planets such as Jupiter and Saturn. However, its high temperature may cause some of its gas to be in a plasma state.

4. Is it possible for life to exist on this giant planet?

It is highly unlikely that life could exist on this giant planet due to its extreme temperatures and lack of solid surface.

5. How did scientists determine the temperature of this giant planet?

Scientists used a combination of data from the planet's parent star and observations from telescopes to calculate the planet's temperature. They also used computer simulations to model the planet's atmosphere and heat distribution.
