Venus is sometimes called Earth’s twin because Venus and Earth are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets.
Likewise, What is the hottest planet?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)

Is Jupiter a failed star?
« Jupiter is called a failed star because it is made of the same elements (hydrogen and helium) as is the Sun, but it is not massive enough to have the internal pressure and temperature necessary to cause hydrogen to fuse to helium, the energy source that powers the sun and most other stars.
What planet is under Earth?
Although Venus is the planet that comes closest to Earth as it sweeps by on its orbit, Mercury stays the closest to Earth the longest, according to a commentary published Tuesday (March 12) in the magazine Physics Today.
Can we live on the sun?
But if you take a look around, there’s nothing here for you to actually land on, because the sun doesn’t have any solid surface to speak of. It’s just a giant ball of hydrogen and helium gas. … They’re cooler regions of gas, some as large as the entire Earth.
Does Mars have oxygen?
Mars’ atmosphere is dominated by carbon dioxide (CO₂) at a concentration of 96%. Oxygen is only 0.13%, compared with 21% in Earth’s atmosphere. … This process allows us to convert these abundant materials into useable things: propellant, breathable air, or, combined with hydrogen, water. »
Can we live on Titan?
Habitability. Robert Zubrin has pointed out that Titan possesses an abundance of all the elements necessary to support life, saying « In certain ways, Titan is the most hospitable extraterrestrial world within our solar system for human colonization. » The atmosphere contains plentiful nitrogen and methane.
Is Earth the only planet with life?
The third planet from the sun, Earth is the only place in the known universe confirmed to host life. With a radius of 3,959 miles, Earth is the fifth largest planet in our solar system, and it’s the only one known for sure to have liquid water on its surface. … Earth is the only planet known to maintain life.
