측정값

정보 102광년. 가로지르는 데 걸리는 시간:

2026-10-25까지 1년 동안 바깥쪽으로 이동한 속도의 보이저 1호(JPL Horizons). 운전: 쉬지 않고, 연료 보급 없이.

iot Dra b — 12 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 510 days; about 350 °C, hotter than boiling water; found in 2002 by radial velocity.
iot Dra c — 12 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 68 Earth years; about −100 °C, below freezing; found in 2021 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.
