description GJ 1061 Overview
GJ 1061 is a red dwarf star of spectral class M5.5V located approximately 12 light-years away from Earth in the southern constellation of Horologium. It is a relatively cool and dim star, possessing only a fraction of the Sun's mass and radius, which makes it invisible to the unaided human eye. Astronomical observations have confirmed the presence of three Earth-sized exoplanets orbiting the star. At least two of these planets are situated near the system's habitable zone, where conditions could theoretically allow for the existence of liquid water.
help GJ 1061 FAQ
Which GJ 1061 planet is in the habitable zone?
GJ 1061 d lies within commonly used estimates of the star's liquid-water habitable zone, while GJ 1061 c is near its warmer inner edge. A habitable-zone orbit does not prove that either planet has water, an atmosphere, or life.
How were the planets around GJ 1061 discovered?
Astronomers detected their gravitational pull through radial-velocity measurements rather than watching them transit the star. The discovery was announced by the Red Dots project using precision observations from the HARPS spectrograph.
Are the three GJ 1061 planets actually Earth-like?
Their measured minimum masses are roughly 1.4 to 1.8 times Earth's, making rocky compositions plausible. Their surfaces and atmospheres have not been directly characterized, so calling them Earth-sized does not mean they resemble Earth environmentally.
Why is GJ 1061 important for exoplanet research?
At only about 12 light-years away, it is one of the nearest compact systems containing low-mass planets. Its proximity makes it a valuable target for future attempts to constrain planetary atmospheres and orbital conditions.
