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。

HD 68475 b — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 21 Earth years; about −190 °C, below freezing; found in 2026 by radial velocity.

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.
