dV also called delta V is the change in velocity required. Higher means more fuel is required and so making the rocket is harder. The earth orbits the sun at a very high speed and so to get to a planet much further inward requires slowing down a lot. You can look up escape velocity which is the velocity required to exit a gravitational body completely.

I've been using infinitime for about 2 years now and recoment it. I think the pinetime can run both infinitime and wasp-os but you'll need a ex-wearos watch for asteroids-os.
