Rogue Planet Devours Material at Record Rate of 6 Billion Tons Per Second
Cha 1107-7626 is growing at about 6 billion metric tons per second with recurring accretion bursts, suggesting rogue planets form like stars but remain substellar.
- On October 2, 2025, the European Southern Observatory reported Cha 1107-7626, rogue planet, accreting gas and dust at six billion tonnes per second.
- Researchers say Cha 1107-7626 appears to have formed like a star, with magnetic activity driving the dramatic mass infall during its accretion burst among free-floating planetary-mass objects .
- Using the VLT and JWST, astronomers recorded Cha 1107-7626 brightening by around 1.5-2 magnitudes this year, with a mass five to 10 times the mass of Jupiter.
- The burst persisted for at least two months, indicating a peak accretion rate persisting for at least two months and suggesting a potentially recurring EXor-type burst.
- The finding challenges models and highlights that this is the strongest growth rate ever recorded for a planetary-mass object, while rogue planets potentially number trillions in the Milky Way and 20 times more rogue planets than stars.
