Forget Mars, we should go to planet K2-18 b

Unlike Mars, this planet has CO2 and possibly water, which is essential for our own survival, unless we won't be welcomed by the indigenous people there.

Got a spare million years to get there?

I've got my peanut butter sandwiches ready.

Do i pack clothes for a cold planet, or warm?


Actually, I'll probably grow old and die on the spaceship itself, so doesn't matter.

Is planet K2-18b trending on Twitter, Instagram, or any other social media?
I am asking because the only social media I learned to utilize is TTW.

In order to enhance my knowledge about this planet, I applied the Srsh Investigation Method, i.e., browse Wikipedia.

And I got this


The article says that this (exo)planet is also known as EPIC 201912552 b, so I believe that @MichaelNadal would be very interested in it.
It's 124 light years far form earth. So travelling at the speed of light, it takes you 124 years to get there.


I copy below

K2-18b, also known as EPIC 201912552 b, is an exoplanet orbiting the red dwarf K2-18, located 124 light-years (38 pc) away from Earth. The planet is a mini-neptune about 2.6 times the radius of Earth, with a 33-day orbit within the star's habitable zone. This means it receives about a similar amount of starlight as the Earth receives from the Sun. Initially discovered with the Kepler space telescope, it was later observed by the James Webb Space Telescope in order to study the planet's atmosphere.

In 2019 the presence of water vapour in K2-18b's atmosphere was reported, drawing attention to this system. In 2023, the James Webb Space Telescope detected carbon dioxide and methane in the atmosphere of exoplanet K2-18b. JWST’s data has been variously interpreted as a water ocean or a magma ocean planet with a hydrogen-rich atmosphere, and a gas-rich mini-Neptune. K2-18b has been studied as a potential habitable world that, temperature aside, resembles more a gas planet like Uranus or Neptune than Earth.

What if the pilot and copilot fall asleep for 30 minutes simultaneously and the ship lands up in another galaxy.
No chance of that. Warp drive won’t get us to the next galaxy. It’s 2.5 million light years away.

But if we wait another 5 billion years, the Andromeda galaxy will collide with our own galaxy. Hold off on buying your ticket to Andromeda until then.
