Answer:
Venus, Earth and Mars
1. Their similarities are: they are planets, having individual paths to orbit, and they are revolving around the sun. Differences: venus is closer to the sun, earth is after the venus and mars is after the earth. But one thing is that the earth is more beautiful than venus and mars.
2. What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
-After the Earth, Mars is the most habitable planet in our solar system due to several reasons: Its soil contains water to extract. It isn't too cold or too hot. Gravity on Mars is 38% that of our Earth's, which is believed by many to be sufficient for the human body to adapt to.
-Incredibly, however, is that early in Venus' history, the planet may have actually been habitable, according to models from researchers at NASA's Goddard Institute for Space Studies and other studies. Venus' surface is extremely dry
