Joint ground- and space-based observations reveal Saturn-mass rogue planet
Simultaneous ground- and space-based observations of a newly discovered free-floating planet have enabled direct measurement of its mass and distance from Earth, according to a new study. The findings offer insights into the diverse and dynamic pathways by which planets can be cast adrift into interstellar space.
Although studies to date have only revealed a handful of such free-floating p Galileo satellites ride Ariane 6 to boost Europe navigation resilience
