측정값

정보 369광년. 가로지르는 데 걸리는 시간:

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

PDS 70 b — 22 times Earth's width, a giant, Jupiter-sized or more; its year lasts about 120 Earth years; about 1,100 °C, hot enough to melt rock; found in 2018 by imaging.
PDS 70 c — 22 times Earth's width, a giant, Jupiter-sized or more; about 780 °C, hotter than boiling water; found in 2019 by imaging.

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.
