Seus planetas

DMPP-1 e — 1.9 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 6 days; about 1,000 °C, hot enough to melt rock; found in 2019 by radial velocity.
DMPP-1 c — 3.3 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 10 days; about 970 °C, hotter than boiling water; found in 2019 by radial velocity.
DMPP-1 b — 4.3 times Earth's width (estimated from its mass, not measured), Neptune-sized; its year lasts 18 days; about 600 °C, hotter than boiling water; found in 2019 by radial velocity.
DMPP-1 d — 2 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 3 days; about 1,400 °C, hot enough to melt rock; found in 2019 by radial velocity.
