इसे कैसे खोजा गया
2024 में त्रिज्य वेग द्वारा खोजा गया पहला ग्रह (NASA एक्सोप्लैनेट आर्काइव)।
इसके ग्रह
Barnard c — 0.7 times Earth's width (estimated from its mass, not measured), smaller than the Earth; its year lasts 4 days; about 130 °C, hotter than boiling water; found in 2025 by radial velocity.
Barnard b — 0.7 times Earth's width (estimated from its mass, not measured), smaller than the Earth; its year lasts 3 days; about 170 °C, hotter than boiling water; found in 2024 by radial velocity.
Barnard e — 0.6 times Earth's width (estimated from its mass, not measured), smaller than the Earth; its year lasts 7 days; about 67 °C, between freezing and boiling; found in 2025 by radial velocity.
Barnard d — 0.7 times Earth's width (estimated from its mass, not measured), smaller than the Earth; its year lasts 2 days; about 210 °C, hotter than boiling water; found in 2025 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.
