I've often wondered if it would be possible to spin Venus faster to shorten its day. Possibly by firing millions of large asteroids past Venus at just the right angle.

Added bonus is that you can mash all those asteroids together to give Venus an Earthlike moon.

Plus I wonder how such large scale gravitational engineering would affect the rest of the solar system.

About 323 million times the energy humanity produces in a year to spin up Venus [0] so probably not anytime soon.

Thank you for a super interesting link!

It briefly mentioned the equatorial bulge that other, faster spinning, planets possess. Would it greatly damage the planet to spin it up?

I also didn't know that Venus' rotational energy is so low that we "could" actually spin it the correct way without spending much more energy.
