Mercury is the smallest planet in the Solar System and is full of many mysteries. What intrigues you the most about the planet closest to the sun?

The shot at 02:43 is crazy, Mercury is sooo far from the sun but in this shot it looks like it's as far as our moon to earth. Makes you realise how HUGE our sun is.

Pluto: *_They ask you how you are and you just have to say that you're fine and you are not really fine but you just can't get into it because they would never understand._*

i didn't know that people actually cared about me-

What if aliens lived in Mercury, they would have a thin voice because of Helium 😂

I love how National Geographic portrays every planet as special and unique in its own way. If I was the planet I would feel really appreciated <3

It's weird that you never mentioned Mercury's rotation. While it takes Mercury 88 Earth days to revolve around the Sun, it takes almost 58 days & 15 hours for the planet to rotate. So 1 Earth day in Mercury is almost 59 Earth days.

Pluto: Am I a joke to you?

What is so amazing, humans are able to study all these so well. Bless us

If Earth is the third planet from Sun after Mercury and Venus
Doesn't that make every country a third world country?

The size of the core and atmosphere that contains oxygen surprises me. I wonder how can Nasa tells us the fact about the size of Mercury's core? Like what method did they use?

[MrPatrick]

I wanna know how they discover the composition of the planets.

[planetarydevinenature]

The solar system, planets and space I have an interest in. Thanks for sharing the info.

The bigger the core is the more it will shrunk.

After so many years in school. I found out that it's easier to learn here
