Definition of moonlet in US English:



  • 1A small moon.

    • ‘The international team found signs of four such moonlets in one small segment of Saturn's brightest ring, called the A ring.’
    • ‘In fact, little moonlets may constantly form and be broken apart.’
    • ‘It's unlikely that moonlets this large were formed through gradual buildup of space material.’
    • ‘In 1856 the British astronomer James Clerk Maxwell refined that hypothesis, arriving at an interpretation more in keeping with the satellite pattern elsewhere evident in the solar system: not millions of rings but millions of moonlets.’
    • ‘For instance, the new moonlet might be quite porous, like an orbiting icy rubble pile. Other moons near the outer edge of Saturn's rings - like Atlas, Prometheus and Pandora - are also porous.’
    • ‘The moonlets range from 32 km to just six kilometres in diameter, the team said in the British weekly, Nature.’
    • ‘Both were rocks, the outermost with two moonlets and a small cloud of large asteroids, the innermost with none.’
    • ‘Essentially, rings are just thousands of tiny moonlets that orbit a planet and don't clump back into larger objects.’
    • ‘‘The interiors of the tiny moonlets, which have been shielded from contamination by the continual collisions with each other, are the source of purer water ice,’ he said.’
