測定値

概要 2,380光年. 横断するには:

2026-10-25までの1年間に外向きに進んだ速さでのボイジャー1号（JPL Horizons）。走行条件：休みなし、給油なし。

Kepler-69 c — 1.7 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 240 days; about 26 °C, between freezing and boiling; found in 2013 by transit.
Kepler-69 b — 2.2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 14 days; about 510 °C, hotter than boiling water; found in 2013 by transit.

NASA Exoplanet Archive, Planetary Systems Composite Parameters (fetched 2026-11-02). Composite values: where a planet's size or mass was not measured, the archive estimates it from the other.
This research has made use of the NASA Exoplanet Archive, which is operated by the California Institute of Technology, under contract with NASA under the Exoplanet Exploration Program.
