Planet Mercury

Mercury is the closest planet to the Sun in our solar system, orbiting approximately 36 million miles away from it. It is the smallest and innermost planet, taking about 88 Earth days to orbit the Sun.

Surface area of planet Mercury is 7.48×10^7 km2

The Mariner 10 has visited mercury 3 times. Its major mission was to photograph Venus but got off orbit and ended up photographing Mercury. After orbiting the sun it met up with Mercury again in 176 days. In another 6 months the Mariner 10 saw Mercury again. All of this happend between 1974-1975.

Mercury is hot and dry because it is very close to the sun, causing its surface temperature to reach very high levels. The lack of a thick atmosphere on Mercury also contributes to its extreme temperature variations.

Mercury has a diameter of about 4,880 kilometers (3,032 miles) and a circumference of approximately 15,329 kilometers (9,525 miles) around its equator.

(1)The temperature of Mercury is about 100 degree celcius.Generally the human body cannot bear such a high temperature.

(2)Human body needs Oxygen to survive.It is an essential factor for our body.

(3)Recently scientist have discovered that there is no Oxygen on planet Mercury.So ,thats why we have to wear Oxygen mask on Mercury.

Mercury has three main phases: "new," "first quarter," and "full." During a "new" phase, Mercury is between the Earth and Sun, so it appears dark. During the "first quarter" phase, we see half of Mercury illuminated. And during the "full" phase, the entire side facing Earth is illuminated.

Yes, Mercury is a low-density planet with a density of about 5.4 grams per cubic centimeter. This relatively low density is due to its small size and composition, which is primarily made up of rocks and metals.

Using the 2/5 figure, which is a rough estimate, a statue weighing 225 tons would weigh 90 tons on Mercury.

225 x 2/5 = 450/5 = 90

The moon, Mercury, and Mars are all so small that over time they have lost much of their internal heat and have become geologically dead.

Unlike the Earth which is geologically alive, mercury has no tectonic or core activity.

There are no tectonic plates

There are no volcanos

There is no wind erosion

There is no frost erosion

There are no rivers and therefore no water erosion

There is no change due to living organisms eg sedimentation

Mercury is the closest planet to the Sun.

No, Mercury cannot sustain life as we know it. Its proximity to the sun means extreme temperatures, ranging from very hot to very cold, and its very thin atmosphere, mostly made up of gases like oxygen and hydrogen, is not capable of supporting life.

Earth is a terrestrial planet as opposed to a Jovian planet that is made up of mostly gas which is Helium and hydrogen and you should know its a Terrestrial planet cause of its rocky surface and its inner core also it's size.

Mercury doesn't have much of an atmosphere. The atmospheric pressure there is a trillion times less than the pressure on earth. It is made up of 42% oxygen, 29% sodium, 22% hydrogen, 6% helium, 0.5% potassium, and trace amounts of argon, nitrogen, carbon dioxide, water vapor, xenon, krypton, and neon.

The densities of the planets generally decrease as you travel from Mercury to Neptune. Mercury and Earth have similar average densities, while Venus and Mars have lower densities. The gas giants - Jupiter, Saturn, Uranus, and Neptune - have much lower average densities due to being composed mostly of hydrogen and helium gases.

Mercury has little erosion on its surface because it lacks a significant atmosphere to support weathering processes like wind and water erosion. Additionally, the planet's weak gravitational pull makes it difficult for particles to be lifted and transported across its surface. Finally, the lack of substantial volcanic activity on Mercury means there are fewer opportunities for landforms to be reshaped or erased.

Mercury has a very slow rotation on its axis, taking about 59 Earth days to rotate once. This means that a day on Mercury is longer than a year on Mercury. Its rotation is also unique in that it is in a 3:2 spin-orbit resonance, resulting in strange patterns of movement.

No, Mercury is the closest planet to the sun.

It is very hot and rocky, there is no atmosphere and it is the smallest because Pluto is no longer known as a planet. Mercury is 430 degrees during the day and -170 degrees at night. The sky is black on Mercury and it would take ~4 months to reach Mercury.

I hope this answers many of your Mercury questions. I collected my information in a book from the library.

Earth has an atmosphere, water, and plate tectonics. Rivers, glaciers and, to a lesser degree, wind, are constantly weathering Earth's surface, carving valleys and breaking down mountains. Moving tectonic plates thrust up mountain ranges and recycle the ocean floor. Volcanoes create fresh, new surface material.

Mercury and the moon have none of these features. They are geologically dead. Collisions with asteroids and comets are the only significant forces that shape their surfaces, so they are covered in impact craters. Other than these craters, the surfaces of these objects have not changed since they first formed. Many of the craters themselves formed when the solar system was young and collisions were more common.

Planets are categorized as either Jovian or terrestrial based on their composition and physical characteristics. Jovian planets are large gas giants with no solid surface, while terrestrial planets are rocky with a solid surface. Jovian planets are typically further from the sun than terrestrial planets.

Rotation on its axis takes about 58.6 Earth days and revolution around the Sun takes about 88 Earth days.

Some of the notable craters on Mercury include names like Shakespeare, Beethoven, Debussy, and Caloris. Caloris Basin is one of the largest and most well-known craters on Mercury.

The average temperature on Mercury can vary dramatically, ranging from about -280°F (-173°C) at night to around 800°F (427°C) during the day due to its thin atmosphere and lack of significant heat retention.

On Mercury, a person who weighs 110 pounds on Earth would weigh approximately 41 pounds due to Mercury's lower gravity. Mercury has only about 38% of the gravity compared to Earth.

The element mercury is a metal. The planet Mercury is rocky.
