About this world
KOI-1783.02 is a Neptune-like planet orbiting KOI-1783, a yellow, Sun-like star 2.82 thousand light-years from Earth. It is about 5.4 times the size of Earth and holds 15 Earth masses. It completes an orbit every 284 days at 0.87 AU from its star.
Its equilibrium temperature is about 321 K (48 °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. KOI-1783 has 2 known planets; the others are KOI-1783.01.
