About this world
Kepler-1700 b is a sub-Neptune orbiting Kepler-1700, a yellow-white F-type star 2.34 thousand light-years from Earth. It is about 2.9 times the size of Earth. It completes an orbit every 234 days at 0.76 AU from its star.
Its equilibrium temperature is about 329 K (56 °C): too cold for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2020 by transit with Kepler. A planet crosses its star and dims it by a tiny, periodic fraction.
