It will give you three temperature points and four steel, and let you take eight plants from another player.

In actuality, yes, but to a fairly negligible degree. You’d be adding some energy and maybe a bit of greenhouse effect to the atmosphere, so it might get a degree or two warmer from the impact, but not permanently. And you’d be adding mass, but not nearly enough to have a noticeable increase in gravity.

Darn it. We can work on Venus then. There must be something we can do

Well, Phobos alone might not do the whole trick, but there’s lots of other asteroids near there. I’ve heard there’s this “belt” thing?

Worth a shot. Or we can take this belt and mash it into a new planet

I have a plan for Venus.

  1. We put a bunch of mirrors at the Venus-Sun Lagrange point #1. Reflect light away from Venus. Cool it down until the atmosphere freezes. (This is a 1000 year project.)
  2. Once the surface pressure is down to 1 Bar or 14.7 PSI or 101 kPa or whatever, start building chemical plants on the surface to convert those puddles of liquid nitrogen and frozen blocks of CO2 and sulfuric acid into solid minerals, so the air pressure won't rise when the heat is turned back on.
  3. Turn the heat back on, by turning some of those mirrors sideways to the Sun.
  4. Introduce life. Hydrogen from sulfuric acid and oxygen from CO2 make water. Chemical plants from step 2 have made some fertilizer. Plant some plants. Water them.
  5. Bring in the people.

It might take 2000 years total, but we can remake Venus in Earth's image.

Sounds like a good investment for the future of humanity. We must tell Elon at once!
