Definition of moonlet in US English:

moonlet

noun

  • 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.’
