How many Mercury’s can the Sun fit?
Mercury is the smallest planet in our Solar System, having a diameter of only 4.879 km / 3.032 mi, and a radius of 2.439 km / 1.516 mi, and only 0.055 Earth masses. It would take around more than 21.2 million Mercury-sized planets to fit inside the Sun.
How many times Mercury is bigger than Earth?
The mass and volume of Mercury is only about 0.055 times that of Earth. But because Mercury's small mass is enclosed inside of a tiny body, the planet is the second densest in the solar system, weighing in at 5.427 grams per cubic centimeter, or 98 percent of the density of our planet. Only Earth is denser.
Is Mercury 18 times the size of Earth?
Mercury is the smallest planet in both mass and diameter. It is about 18 times less massive than Earth. With a diameter of about 3,032 miles (4,879 kilometers), Mercury is not quite two fifths the size of Earth. It is only about a third larger than Earth's Moon.
How many Mercury’s can fit in Jupiter?
24,462 Mercurys In terms of volume, you could fit 24,462 Mercurys inside Jupiter. Jupiter even has 5,750 times more mass than Mercury. Now let's take a look at their composition. Mercury is a rocky terrestrial planet, with a high density.
How many moons fit in the Earth?
50 moons THE MOON IS SMALLER ACROSS (IN DIAMETER) THAN THE UNITED STATES IS WIDE. If the Earth were hollow, about 50 moons would fit inside.
Can you breathe on Mars?
If you tried to breathe on the surface of Mars without a spacesuit supplying your oxygen – bad idea – you would die in an instant. You would suffocate, and because of the low atmospheric pressure, your blood would boil, both at about the same time.
Can we land on Mercury?
Could humans land on Mercury's surface? In spite of being so close to the Sun, and wild swings in extreme temperatures, humans could technically walk on the planet's surface. Mercury's slow rotation means it takes 59 Earth days for it to turn around once.
What is the Earth’s twin planet?
Venus Venus is often called "Earth's twin" because they're similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
Is Mercury bigger than Pluto?
In case you're wondering, though, Mercury is still significantly larger than the dwarf planet Pluto: Pluto's equatorial diameter is just 2,302 km, about half Mercury's width.
How many Venus can fit in the Sun?
1.5 million planets The diameter of Venus is 12,103 km, while the diameter of the Sun is 1.4 million km. In other words, the Sun is 115 times larger than Venus. You could fit about 1.5 million planets the size of Venus inside the Sun.
How many Pluto’s can fit inside Earth?
154 Plutos can fit in Earth. Earth has a radius of 6,371 kilometers and Pluto has a radius of 1,188.5 kilometers.
What if Earth had two moons?
If Earth had two moons, it would be catastrophic. An extra moon would lead to larger tides and wipe out major cities like New York and Singapore. The extra pull of the moons would also slow down the Earth's rotation, causing the day to get longer.
Can we breathe on Titan?
Titan's nitrogen atmosphere is so dense that a human wouldn't need a pressure suit to walk around on the surface. He or she would, however, need an oxygen mask and protection against the cold—temperatures at Titan's surface are around minus 290 degrees Fahrenheit (minus 179 Celsius).
Can plants grow on Mars?
In “The Martian,” Mark Watney uses the Martian soil to grow potatoes in the controlled environment of the “Hab.” In reality, the soil on Mars actually does have the nutrients plants would need to survive on Mars!
Does diamonds rain on Jupiter?
But in the dense atmospheres of planets like Jupiter and Saturn, whose massive size generates enormous amounts of gravity, crazy amounts of pressure and heat can squeeze carbon in mid-air — and make it rain diamonds.
Why does Neptune rain diamonds?
Take the conundrum, for example, of how the chemical reactions inside of Neptune and Uranus may cause diamonds to rain down on the planets' cores. Under immense pressure deep below the planets' surfaces, carbon and hydrogen atoms are smushed together, forming the crystals.
Do we have 2 suns?
Our Sun is a solitary star, all on its ownsome, which makes it something of an oddball. But there's evidence to suggest that it did have a binary twin, once upon a time.
Who is Earth’s evil twin?
Venus Venus has been called Earth's "evil twin" because it is about the same size as Earth and probably was created out of similar stuff; it might have even had at one time oceans of liquid water. But Venus appears to have suffered a runaway greenhouse effect.
Is Titan bigger than Mercury?
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). Titan's atmosphere is made mostly of nitrogen, like Earth's, but with a surface pressure 50 percent higher than Earth's.
What is our galaxy name?
The Milky Way The Milky Way gets its name from a Greek myth about the goddess Hera who sprayed milk across the sky. In other parts of the world, our galaxy goes by other names. In China it's called the “Silver River,” and in the Kalahari Desert in Southern Africa, it's called the “Backbone of Night.”
How many moons fit in the Sun?
This means the number of Moons required to fill the Sun is 50 times more than the number of Earths required. So, a total of 65 million Moons can fit inside the Sun.
How many Mars could you fit in Earth?
Mars is actually smaller than the Earth! The radius of Mars is 3,389.5 km, which is just over half that of the Earth's: 6,371 km. If you assume they're both perfect spheres, this means that you can actually fit about 7 Mars's inside Earth!
What if Earth had a blue sun?

What if we had 2 suns?
When both suns were up, days would be much brighter. Nights would be different too because the suns would sometimes set at different times (source: Warren). Still others suggest that the number of eclipses would increase as one sun moved in front of the other, maybe as often as once a week or so.
Does it rain on Titan?
While Earth rain falls at about 20 miles per hour (9.2 meters per second), scientists have calculated that rain on Titan falls at about 3.5 miles per hour (1.6 meters per second), or about six times more slowly than Earth's rain. Titan's raindrops can also be pretty large.
Can we survive on Pluto?
Potential for Life. The surface of Pluto is extremely cold, so it seems unlikely that life could exist there. At such cold temperatures, water, which is vital for life as we know it, is essentially rock-like. Pluto's interior is warmer, however, and some think there could even be an ocean deep inside.
Does it rain on Mars?
Because of Mars' very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away. atmosphere as well as around mountain peaks. No precipitation falls however.
Is water on Mars drinkable?
It's official. NASA scientists have found evidence of present-day liquid water on Mars. But before you start thinking about a second home there, know this: that water isn't drinkable. It's chock full of salts called perchlorates that can be toxic to humans.
What rains on Mars?
Because of Mars' very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away. atmosphere as well as around mountain peaks. No precipitation falls however.
What rains Uranus?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
