You can tell that an organism is related to another organism by looking at their DNA. If they are similar, they are related. Another way to see if they look similar. For example, we are related to chimpanzees because we look similar and have similar DNA.

It depends; If you're asking for very temporary moments on the planet, it would be mercury, because its temperature ranges from 427 degrees to -180 degrees Celcius. If you were to stand just in the right spot at just the right time, its temperature would be the same as the earth's temperature.
But if you are asking about longer periods of time, it would be Mars. Its average temperature is around -60 degrees celcius, but its summer can get up to 20 degrees celcius.
