Mercury has a radius of about 2,440 km, and its surface area is 74,797,000 km2. Its mass is 3.30 × 1023 kg. Mercury is the smallest major planet in both size and mass.

Can we land on Mercury?

First, getting there: “You essentially need three rockets to get to Mercury,” Hauck said: one to get off Earth, one to get from Earth to Mercury and one to carefully land on the planet (because it lacks an atmosphere that can slow down a spacecraft).

Is Mercury bigger than Titan?

Titan is larger than the planet Mercury and is the second largest moon in our solar system. Jupiter’s moon Ganymede is just a little bit larger (by about 2 percent).

What is the hottest planet?

Venus’ thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead.

Can humans live on Mercury?

Mercury is not a planet that would be easy to survive on but it may not be impossible. It is worth noting that without a space suit you would not survive very long at all, due to a lack of atmosphere. On top of this Mercury has one of the largest changes in temperature in the Solar System.
