Ultra-short period (USP) rocky planets, which orbit their stars in less than a day, are rare, especially around red dwarfs. TOI-4552 b is a newly validated Earth-sized planet with a 0.3-day orbit around a quiet M4.5V red dwarf just 90 light years away.

Really surprised it’s not hit the roche limit.Â
How far is it from its star? The article doesn’t seem to sayÂ
I’m off to work, hon. See you next year.
Cuál es su distancia con la estrella?, me parece que en el artÃculo no dice
Earth-sized…8 hours?! Holy shit
A birthdayparty could only be a fart. Nice.Â
Bet it really sucks trying to get all your gardening done in that 2 minute springtime every year…
Can someone explain the photo to me? I assume it’s a digitally rendered photo, but if so, why make it so small and blurry?
This got me wondering….is there a fastest measured object in the universe?
Just 90 light years away.. lol we cant even survive 0.1% the distance of 1 light year with existing technology
I see… so I clocked in at work today 3-21-26 then clocked out at 3-21-27. Ok cool
Do we have any idea what the climate on that planet might be like?
So, how does gravity of the planet work in such a case, I mean the speed of the thing must be bonkers for such a large mass, would this influence the gravity of the planet and its capacity to hold onto things.
People on TOI-4552B
“AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA”
Step One: Open a birthday candle store.
Step Two: PROFIT!!
Now how long do it’s days last?
Holy, even Jupiter has a longer day
I will always be doing my taxes there.
We should all come back to this threat to celebrate a Happy New Year on TOI-4552 b exactly 8 hours after this post was published.
How long would it take to release the next Severance season on that planet?
Don’t forget, honey, we’re having everyone over at 8:30 for the Superbowl party, then we’re at your mom’s for Easter at 10am, then my parents at noon for the fourth, then you’re taking the kids trick or treating at 2pm, then we’re back at your mom’s for Thanksgiving at 3pm, then your dad’s at 3:30 for Christmas and New Year’s Eve.
No way this thing is anywhere near as round as that picture
AI generated image?
The link and the news is valid, and interesting.
Wait are they using jira tickets to name planets?
That’s a shorter orbital period than Io. The tidal forces on that planet must be very high. I’m imagining giant volcanic eruptions, much larger than on Io, constantly occurring.
Wouldn’t they be most common around red dwarfs? How would they get so close around larger stars?
I think you mean an “Orbit” that lasts 8 hours : )
So at what speed is it zipping around the sun? The centrifugal force gotta be crazy
I find these announcements rediculous. This is all in theory, since they can’t actually see the planet, all they can see are shadows as the planets cross in front of stars. They can’t tell what gasses their atmosphere (if there even is one) have, all they have are computer-created colors that MIGHT show the makeup of gasses.
Their theories have never been proven simply because there hasn’t been a single planet they have theorized that any one has been too to prove it their theories.
I find it interesting to have these theories but don’t write articles where you are positing these theories as facts.
Probably that’s not an actual photo of it.
How long are the other years?
The thing is exoplanets with really short orbital periods are also the easiest to find.
“This little maneuver is going to cost us 408 hours.”
Finally my 2 seconds are impressive now
Bro, if you jump correctly you may make it escape the orbit of the sun.
I know it’s fun to say, but it does not have a year that lasts 8 hours, and it’s just tiktok bait when someone says it does at this point.
