TrES-2
system
TrES-2 — a Sun-like star ~702 light-years away in Draco, host to the DARKEST known planet. TrES-2 b (also Kepler-1 b) reflects less than 1% of the light that hits it — blacker than coal or black paint — so it is a nearly invisible world, glowing only a faint dull red from its own heat. Descend to explore the dark planet.

How we know
- Note
- A real star system, shown at its measured position in the galaxy. Its star and confirmed planets — their measured sizes and how each was found — are on the cards inside; descend to explore them. Distances follow Gaia parallax; planet data follow the NASA Exoplanet Archive.
Discovery & history
- Name
- A designation from the Trans-Atlantic Exoplanet Survey (TrES); also Kepler-1 b, the first object in the Kepler catalogue.
TrES-2 b was one of the first transiting planets found (2006) and happened to sit in NASA's Kepler field (as Kepler-1 b). Kepler's exquisite photometry showed it reflects under 1% of its starlight — the lowest albedo of any planet then measured — its dark, hot atmosphere inferred to swallow light with little to reflect it.
