How many Earth’s can fit in Mercury?

If you could unwrap Mercury, it would be almost twice the area of Asia (44 million square km). And the volume of Mercury is 6.1 x 1010 km3, which works out to 5.4% the volume of Earth. In other words, you could fit Mercury inside Earth 18 times over and still have a bit of room to spare.

What is the hottest planet?

Even though Mercury is closer to the Sun, Venus is the hottest planet in our solar system. Its thick atmosphere is full of the greenhouse gas carbon dioxide, and it has clouds of sulfuric acid. The atmosphere traps heat, making it feel like a furnace on the surface. It’s so hot on Venus, the metal lead would melt.

Why is Mars red?

‘ So where does that redness come from? Well, a lot of rocks on Mars are full of iron, and when they’re exposed to the great outdoors, they ‘oxidize’ and turn reddish – the same way an old bike left out in the yard gets all rusty.

How many suns can fit in a black hole?

Some black holes, called supermassive black holes, may have as much matter as 1000 million Suns!

How many galaxies are there?

If we made the most straightforward estimate using today’s best technology, we’d state there are 170 billion galaxies in our Universe. But we know more than that, and our modern estimate is even grander: two trillion galaxies.

Will Mars lose a moon?

Deimos is in the second place among Solar System planets’ moons. Mars will lose its moons. Phobos that slowly approaches Mars will crash into the planet or break up into a ring. Deimos, on the contrary, moves away from Mars and eventually will leave the planet’s orbit.

Can you survive on Mars for 2 minutes?

It’s relatively cool with an average annual temperature of -60 degrees Celsius, but Mars lacks an Earth-like atmospheric pressure. Upon stepping on Mars’ surface, you could probably survive for around two minutes before your organs ruptured.

How long can you breathe on Mars?

Meanwhile, Mars has almost no oxygen; it’s only one-tenth of one percent of the air, not nearly enough for humans to survive. If you tried to breathe on the surface of Mars without a spacesuit supplying your oxygen – bad idea – you would die in an instant.

Does it rain in Mars?
