What is the real diameter of Mercury?

What is the real diameter of Mercury?

Radius, diameter and circumference Mercury’s diameter is 3,030 miles (4,878 km), comparable to the size of the continental United States. This makes it about two-fifths the size of Earth. It is smaller than Jupiter’s moon Ganymede and Saturn’s moon Titan.

What is Mercury’s mass and diameter?

Distance, Size and Mass Mercury has a radius of 2.439 km or 1516 mi, and a diameter of 4.879 km or 3.032 mi. It is about the size of the continental United States, slightly bigger. It has a mass of about 3.285 × 10^23 kg or about 5.5% that of Earth.

Is Mercury 1/3 the size of Earth?

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 1 18 times the size of Earth?

Mercury has a diameter of 3,032 miles (4,879 km) making it a little more than one third the size of Earth. If Earth were the size of a baseball, Mercury would be about the size of a golf ball.

What Colour is Mercury?

The planets of the solar system are varied in their appearance. Mercury is slate gray while Venus is pearly white, Earth a vibrant blue, and Mars a dusky red.

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. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.

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).

Can we breathe on Mercury?

ROUTES OF EXPOSURE: Elemental mercury is toxic primarily through inhalation of mercury vapors. It is only slowly absorbed through the skin, although it may cause skin and eye irritation.

Is Mercury the 3rd smallest planet?

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

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.

Why is Mercury called the smallest planet?

Smallest Planet: Mercury The smallest planet in regards to both mass and volume is Mercury — at 4,879 km across and 3.3010 x 1023 kg, this tiny world is nearly 20 times less massive than Earth, and its diameter is about 2½ times smaller. In fact, Mercury is closer in size to our Moon than to Earth.

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 Earth 3 times bigger than Mercury?

Earth vs Mercury It has 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. Our Earth is three times bigger than Mercury.

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 18 times smaller than Earth?

Size, Mass and Orbit: The diameter of Mercury is 4,879 km, which is approximately 38% the diameter of Earth. In other words, if you put three Mercurys side by side, they would be a little larger than the Earth from end to end.

Is Mercury 18 times bigger than 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.

What is the real shape of Mercury?

Mercury has a solid, cratered surface, much like the Earth’s moon.

Is it true that Mercury is shrinking?

Like a raisin spinning around the sun, Mercury is shrinking and wrinkling. The planet is now up to 8.6 miles (14 kilometers) smaller in diameter than it was nearly four billion years ago, according to a report released on Sunday. The planet is downsizing because it is cooling.
