description HAT-P-32b Overview

HAT-P-32b is an inflated hot Jupiter exoplanet orbiting the G-type or F-type star HAT-P-32. Discovered in 2011, it is situated in the northern constellation of Andromeda. The planet has one of the largest known radii for its mass class, resulting in an extremely low density. Its significant atmospheric scale height makes it a frequent target for transmission spectroscopy studies to analyze its chemical composition and high-altitude hazes.

help HAT-P-32b FAQ

What kind of planet is HAT-P-32b?

HAT-P-32b is an inflated hot Jupiter orbiting the star HAT-P-32 in Andromeda. Its very large radius and low density make it unusually puffy for a planet with a Jupiter-like mass.

When was HAT-P-32b discovered?

The planet was discovered in 2011 using the HATNet transit survey. A transit occurs when the planet passes in front of its star and slightly reduces the star's brightness.

Why is HAT-P-32b called a hot Jupiter?

It is a gas giant on a close orbit around its host star, so its atmosphere is intensely heated. That short orbital distance also allows astronomers to detect it readily through repeated transits.

Where is HAT-P-32b located?

HAT-P-32b is in the northern constellation Andromeda. It orbits the star HAT-P-32 rather than our Sun, and its unusually inflated radius is the main reason it attracts attention.
