How long will it take for the moon to drift far enough away from earth that the lunar month extends by a day? Or two days?
Working on a worldbuilding project for a dnd campaign, and want to subtly hint that its super far into the future with the lunar calendar. If you also know of any websites that can generate star charts of what the night sky will look like in millions of years, that would also be great.
We’ve sent probes to other worlds. There’s a very small chance we accidentally introduced some of Earths microorganisms to other planets that would still be around in 5 billion years after the sun. We’ve sent all kinds of stuff to Mars which will still be around when our sun turns into a Red Giant eating Mercury, Venus, and Earth. However Mars will have courtside seats to the sun at that point and be baked in high intensity heat and radiation, so I wouldn’t have much hope of any life we introduced there surviving.
We’ve also sent probes into Jupiter. There its unlikely anything could live we brought, but who knows? Lastly we put a lander on Saturn’s largest moon Titan. Its not very hospitable to Earth life there though. Its our best bet though. The only other chances life from Earth would survive is all of the probes we’ve sent out into interstellar space.
