The speed will be related to escape speed of sun. Based on https://en.m.wikipedia.org/wiki/Escape_velocity It will be Vte which is 16.6 km/s (or Ve 42.1). So when object at earth orbit and has lower speed than 16.6 it can’t keep the orbit and will slowly fall into sun.
" Windows 10 EOL doesn’t mean it will stop working. If sims has trouble just use win. "
This, just continue win 10 (or win11 even though they said not run blah blah). I have my whole house with about 4 PC/server all running Debian but I still keep one gaming PC run windows.
