text: To understand Venus clearly, NASA wants to explore Venus on their own. They can either consider the exploration as a risk, or the exploration can be thought out as a challenge that people are willing to take despite the dangers. "On the planet's surface, temperatures average over 800 degrees Fahrenheit, and the atmospheric pressure is 90 times greater than what we experience on our own planet". Humans cannot undergo, let alone survive stepping foot on Venus with these extreme conditions. Earth's "twin" planet also has "the hottest surface temperature of any planet in our solar system". Although there are many dangers to explore Venus, astronomers are fascinated by the idea that Venus has been the most Earth-like planet in our solar system.
