Content: Something else which helps the plants to photosynthesise on Earth is the length of time the planet takes to spin once on its axis. Taking just under 24 hours means that each side of the planet receives sunlight regularly. If we look at a planet like Venus, which takes 243 days to spin on its axis, it means that for a large period of time certain parts of the planet are in complete darkness. So even if the planet could support life, it would struggle to do so. Frank McCown

Originally Answered: Why earth is the only planet in the solar system capable of supporting life? It’s not. We have bacteria on earth that live off rocks deep under ground, they could just as easily live on other planets if they were transported there. There are some sulphur loving extremophiles that could potentially be adapted to live in the clouds of Venus. We have bacteria that live in ice and metabolize iron that could live on mars.
