This Planet Has A 350,000-Mile Comet Tail 🌌

Added: 2026-05-21

[00:00:00]There's a planet right now dragging a comet-like tail of helium 350,000 mi behind it.

[00:00:07]Longer than the distance from Earth to the moon. And nobody fully understood why until recently.

[00:00:14]This is WASP-69b, a Jupiter-sized world orbiting a star about 160 light-years away. It screams around that star once every 3.87 [music] Earth days. That's blindingly close.

[00:00:29]Because it orbits so close, the star's radiation blasts helium atoms right off the planet's atmosphere. That escaping gas, the stellar wind grabs it and sculpts it, bending it into that enormous glowing tail.

[00:00:43]Here's the number that sounds impossible. WASP-69b is shedding roughly 200,000 tons of atmosphere every single second. Every second.

[00:00:54]Now, here's the twist. Despite that staggering loss, WASP-69b won't be stripped bare for billions of years. It will likely outlast our own sun's entire lifespan. This planet is in no hurry to disappear.

[00:01:08]Scientists confirmed all of this using the Keck Observatory in Hawaii. One planet. A tail longer than the Earth-Moon gap. And it's just getting started.

[00:01:19]Follow the deep rabbit hole. The next fact will genuinely disturb you.
