Queue, jumped

In the double-digit parsec/parallax range: Amaury Triaud's LP 890-9. It's got a transit and the orbiting TESS saw it, so it's now TOI-4306. A hundred lightyears out.

LP 890-9 is the second-coldest dwarf known to host planets after also-Triaud's TRAPPIST-1. The planet's year as usual with transits is swift: 2.7 days.

Personally I might not care but today a second planet was found, at 8.5 days, perhaps not transiting. That is habitable-zone. 'Twas found by land telescopes at Tenerife and Chile.

This makes LP 890-9 a candidate for the JWST. Although as the article notes, TRAPPIST-1 will likely come first.
