What the archive holds on this planet

0%

A size. Yes.

A measured mass. Yes.

A density, which decides rock or gas. No.

How far out it orbits. Yes.

A measured temperature rather than a derived one. No.

An eccentricity, so we know if the orbit is a circle. No.

What seeing it actually provides

A position, a brightness, and light that can be split into a spectrum.

Found by Paranal Observatory in 2014.

This is one of the rare planets that has actually been photographed. Fewer than a hundred of the thousands known were found this way, and they are mostly young giants far from their stars.

# Fewer than a hundred planets have been photographed rather than inferred. Does \\

seeing one directly change how real it feels to you?
