Supererde entdeckte den nahegelegenen Roten Zwerg Ross 318 (Gliese 48) in seiner bewohnbaren Zone. Der Planet ist mehr als sechsmal schwerer als die Erde und umkreist den Stern in 40 Tagen. Nur 27 Lichtjahre entfernt.

I love how things are relative. It’s only 27 light years away but the fastest anyone has ever gone is like 25000mph. Please correct my math but that would take *about ¾ of a million years*.
And, 6x the gravity, right?
Another dead, irradiated world. Never trust red dwarfs.
The game Outpost featured these worlds as possible locations to send the colony ship. Before launch you’d pick a series of planets and dispatch probes…choose but choose wisely.
Six times heavier than Earth? It could be impossible to walk on its surface for a human, depending on the planet’s radius. If the world is as dense as Earth, the surface gravity would be about 1.8G, very difficult but walkable a short way. Life forms on a high gravity world may not be very tall, and neither would features like mountains. It would be alien.
‘Habitable zone’ doing a lot of heavy lifting…
Only 27 light years. That’s practically a neighbor in space. It always amazes me how large the universe is.
I truly think that similar gravity will be the biggest deal in the end and changing atmospheres will be the easier part… once we get to the interstellar part of the far future
For a second I thought that was Kerbin
Just need some astrophage and we can go and check it out
Super Earths are not likely to be anything like Earth. Add the fact that it’s a Red Dwarf it’s likely this is either a Dead Irradiated World or a Mini Neptune.
With that mass it’s much more likely a mini Neptune, but very cool find nonetheless.
It’s no Kepler-1649c, which is an actual Earth-sized planet in the habitable zone of a red dwarf.
It should be noted that this picture is an artist’s interpretation and may or may not accurately represent the planet in question. Exoplanets are discovered by the „transit method“ in which the light of a star is measured; as the planet passes in front of the star, the light dims slightly. Actually photographing exoplanets with any surface detail is well beyond our capabilities. Nearby exoplanets can be photographed with telescopes, but they look like faint specks of light.
So… kinda like Eve. But less purple.
Its weird to think how life if it existed there / we were on it, everything would be different but the same physics laws apply
Only 27 light-years? Well, what are we waiting for? Let’s get moving!
Super earth you say? Time for democracy
Only 27 light years away…
You want kryptonians? This is how you get kryptonians…
If it has oil. It’s gonna need some freedom
Ah, Utapau. Careful, there’s thousands of battle droids on the 10th level.
But do we want to get attacked by SEAF and helldivers?
*stares in managed democracy*
Isn’t there a threshold where the planet’s gravity makes escape velocity impossible using any of our currently known thrust methods? We could send a probe there but nothing on the surface could ever leave?
“Only 27 light years away” that’s 159 trillion miles; an unbelievable number for the human brain to comprehend. That would be the equivalent of traveling 6.38 billion times around the earth. It’s such an unbelievable distance that we can never truly comprehend how far away that really is. Still however, it’s really cool that we are able to detect worlds like this and still have some knowledge of it.
„Only“ 27 light years away. Let’s just take a quick jaunt over there and check it out.
Sounds like it would be hot as hell there
