Definition of exoplanet in English:



  • A planet which orbits a star outside the solar system.

    • ‘Many of these exoplanets are large planets that resemble the gas giants of our solar system: Jupiter, Saturn, Uranus, and Neptune.’
    • ‘Could it be an exoplanet in orbit around that young brown dwarf object at a projected distance of about 8,250 million km?’
    • ‘Nevertheless, this unique observing technique opens a new phase in the exploration of exoplanets, or extrasolar planets, say astronomers.’
    • ‘When astronomers study all those exoplanets and the systems they inhabit, it is natural to look to our own solar system as a template for other planetary systems.’
    • ‘The possible exoplanet is orbiting a star known as GQ Lup, thought to be similar to our own Sun, when it was younger.’
