Venus is about 66 million miles away from the Sun, 96.5 percent of the atmosphere is CO2, with a surface temperature of around 872 deg F. Lead would melt on its surface.

Venus would slowly cool if it were farther away from the Sun, but that would depend on how far you move it.

As we increase our greenhouse gases, we would need to move Earth farther from the Sun to maintain the same environmental conditions. I suspect about a a 3-4 million mile shift would be needed right now.

The earth's orbit is elliptical and is closest to the sun at about the December solstice. Jim__ Dec 2019 #6

Thanks. The info that the earth's orbit is elliptical and not round explains a lot. brush Dec 2019 #7
