Kepler-37b: One Of The Smallest Exoplanets Ever Found

追加: 2026-05-19

[00:00:00]200 light years in Lyra, >> [music] >> a world barely 2,000 km across orbits a sun-like star.

[00:00:08]Its name [music] is Kepler-37b.

[00:00:12]A sprint nearly carries you off the surface. The sky here is jet black [music] even at noon. No atmosphere.

[00:00:20]The host is a fierce point in a sky still filled with stars.

[00:00:25]Sharp [music] crater shadows stretch to a horizon that already begins to curve.

[00:00:30]At a fraction [music] of Earth gravity on a world this small, a serious running stride is nearly an escape.

[00:00:37]>> [music] >> Each footfall lifts higher than the last.

[00:00:40]Long enough, fast enough, >> [music] >> and the surface stops pulling back at all. A single piece of rock floating.

[00:00:49]The substance of a world too small [music] to hold itself together.

[00:00:54]A planet that lets things go.

[00:00:57]Silent into the dark.
