description CoRoT-7b Overview

CoRoT-7b is an extrasolar planet discovered in 2009 by the French-led CoRoT space telescope, notable for being the first confirmed rocky exoplanet. It orbits a G-type main-sequence star in the constellation Monoceros at a very close distance. This proximity results in an extremely short orbital period of roughly 20 hours and exposes the planet to intense radiation. The surface temperatures are so extreme that the planet's rocky surface is thought to be partially molten, classifying it as a lava world.

help CoRoT-7b FAQ

Why is CoRoT-7b so important in the history of exoplanet research?

Discovered in 2009 by the French-led CoRoT space telescope, CoRoT-7b holds the distinction of being the first rocky exoplanet ever found. Prior to this, almost all known exoplanets were gas giants similar to Jupiter.

What are the surface conditions like on CoRoT-7b?

The surface conditions on CoRoT-7b are notoriously extreme, with daytime temperatures reaching well over 2,000 degrees Celsius. At these hellish temperatures, the rocky surface is believed to melt, potentially creating oceans of molten lava.

How long does it take CoRoT-7b to orbit its host star?

Because it orbits incredibly close to its host star, CoRoT-7b has an exceptionally short orbital period. It completes a full orbit in just about 20 hours, meaning its entire 'year' is less than one Earth day.

How did the CoRoT space telescope actually spot CoRoT-7b?

The telescope used the transit method, continuously monitoring the brightness of distant stars for tiny, periodic dips in light. CoRoT-7b was detected when it passed in front of its parent star, causing a slight, recurring dimming.
