Astronomers have spotted a cosmic mismatch that has left them perplexed - a really big planet orbiting a really small star. The discovery defies current understanding of how planets form.

The team found the small brown dwarfs lurking among young stars in IC 348, a star-forming cluster in the Perseus Molecular Cloud around 1,000 light-years from Earth.

TOI-6894b's mass—relative to that of its star, that is—challenges the widely held core accretion theory, which posits that newborn planets pull mass from their star's protoplanetary disc.

The small star is called TOI-6894. Most stars in the Milky Way galaxy are small like TOI-6894. It is a red dwarf with only about 20 per cent of the Sun's mass.

WASHINGTON (Reuters) -Astronomers have spotted a cosmic mismatch that has left them perplexed - a really big planet orbiting a really small star. The star is only about a fifth the mass of the sun.
