NASA's Kepler spacecraft, hunting for distant worlds by measuring the slight dimming of starlight as planets pass in front of their parent suns, has found its first multiplanet solar system, researchers announced Thursday.
The Kepler-9 system includes two Saturn-class worlds orbiting in gravitational lockstep close to their star and a possible third planet just a bit larger than Earth that whirls through a hellish "year" in just 1.8 days.
The asteroid zoomed by Earth at a perfectly safe distance of around 1.8 million miles (2.9 kilometers).
Engineers expect to lose contact with the private US moon lander Odysseus on Tuesday, cutting short the mission after its sideways touchdown last week.
NASA announced Tuesday that a $32.7 million Capstone spacecraft intended to try out a skewed lunar orbit had lost contact, but agency engineers are confident
