For the purposes of this simulation, a pure-metal planet has a density of 8 grams per cubic centimeter (the density of iron) and a pure-rock planet has a density of 3 grams per cubic centimeter (an average value for silicate rock). Questions to Consider:
Depending on how cooked you like your hard boiled eggs, the eggs should be done perfectly in 10-12 minutes. That said, depending on your altitude, the shape of the pan, the size of the eggs, the ratio of water to eggs, it can take a few minutes more.. Turn off the heat, keep the pan on the hot burner, cover, and let sit for 10-12 minutes. If you have the type of stove burner that doesn't retain any heat when turned off, you might want to lower the temp to low, simmer for a minute, and then turn it off.
Boil eggs for approximately 20 minutes. Once eggs are hard, drain water and allow eggs to cool. You may also let them sit in cold water for 15 minutes. Peel eggs then cut them long wise. Set hardened egg whites to the side. Put egg yolks in a small to medium size mixing bowl. Mash yolks with a fork.
