Kind: research · Impact: low

## In brief

- UCLA-led astronomers report the first known "disappearing planet", TOI-2535 b, about 1,000 light-years away.
- TOI-2535 b is a hot Jupiter, a gas giant orbiting very close to its host star, completing one orbit in 8.25 days.
- A neighbouring object makes the system wobble like a spinning top, according to the report.

## Why it matters

The finding documents a new kind of planetary system behaviour, which may help astronomers understand how hot Jupiters form and evolve.
