What is the real size of Mercury?

What is the real size of Mercury?

With a radius of 1,516 miles (2,440 kilometers), Mercury is a little more than 1/3 the width of Earth. If Earth were the size of a nickel, Mercury would be about as big as a blueberry. From an average distance of 36 million miles (58 million kilometers), Mercury is 0.4 astronomical units away from the Sun.

Is Mercury bigger than the Moon?

Some similar-sized objects in the solar system These are the eight bodies in the solar system that are between 2,500 and 5,300 kilometers in diameter: Mercury (4,879 kilometers), the Moon (3,475), Io (3,639), Europa (3,125), Ganymede (5,265), Callisto (4,819), Titan (5,150, but it appears 5,550 with its atmosphere), …

What is Mercury’s size and weight?

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.

Is Mercury large or small?

Mercury is the smallest planet in our solar system – only slightly larger than Earth’s Moon.

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).

Can humans walk 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.

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 hot or cold?

It is understood that the sunny side may reach temperatures of 750 to 800 degrees F., while the nighttime temperature plummets to nearly -330 degrees F. The average temperature on Mercury is a balmy 354 degrees F.

Which planet is biggest than Mercury?

The smallest planet in our solar system is Mercury and the largest planet is Jupiter.

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.

How many Earths 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.

Is Mercury bigger than Mars?

So even though Mars is bigger than Mercury, it’s less dense — a rocky planet with a difference.

Is Mercury bigger than Russia?

Although Russia is huge when all things are considered and even if it is almost twice Mercury’s length at 9,000km compared to Mercury’s diameter of 4,878km, when the surface area and volume is taken into account, Mercury is simply much larger.

Is Mercury as big as Mars?

Mercury is the smallest planet in the solar system with a radius of 1520 mi (2440 km). It is smaller than Mars, but bigger than our Moon. It is smaller than Jupiter’s moon Ganymede and Saturn’s moon Titan.

Can we land on Titan?

On January 14, 2005, humans successfully achieved an incredible feat unsurpassed to date. The European Space Agency’s (ESA) Huygens probe, a metal pie-plate looking device 1.3 metres in diameter, parachuted down onto Titan, the largest of Saturn’s moons, and landed unscathed on its surface.

Can humans 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.

Can you breathe on Titan?

It is cold on Titan (surface temperature of about -290 degrees F). And people would need to wear respirators to breathe oxygen, since the atmosphere is mostly nitrogen.

Is Mercury 1 18 times the size of Earth?

Size, Mass and Orbit: The diameter of Mercury is 4,879 km, which is approximately 38% the diameter of Earth.

Is Mercury bigger than Pluto?

In fact, Mercury is closer in size to our Moon than to Earth. 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.

Is Mercury 18 times bigger than Earth?

How Big Is Mercury? Mercury is the smallest of the eight planets in our solar system. It is only a little bigger than Earth’s moon. It would take more than 18 Mercurys to be as big as Earth.

How big is Mercury vs Pluto?

The diameter of Mercury is 4,879.4 km across, while Pluto’s diameter is 2,360 km across. So Mercury is about twice as large Pluto. And just for comparison, Pluto is only 18% the diameter of Earth, while Mercury is 38% the diameter of Earth.
