Mercury, the closest planet to the Sun, rotates three times on its axis every two of its years. ... Despite having temperatures that are hot enough to melt lead, the tilt of the planet's axis allows for ice to exist at its poles.

What is unique about mercury?
Mercury is also the smallest planet in the solar system, measuring just 3,032 miles wide at its equator. That makes it only slightly larger than Earth's moon. Because Mercury is so small and so close to the sun, it is the most elusive of the five planets that are visible to the naked eye.
What are the unusual properties of mercury?
Mercury has a relatively high vapour pressure and the highest volatility of any metal, vapourizing to become a colourless, odourless gas. The metal is a fair conductor of electricity, but a poor conductor of heat. Mercury's atomic number is 80.
What is unusual about HG?
Mercury (chemical symbol: Hg)
Mercury is a dense, shiny, silvery-colored metal whose most unique characteristic is that it is a liquid at room temperature (Fig. 1). The only other element in the periodic table that shares this attribute is bromine (Br).
What does mercury react with?
Like silver, mercury reacts with atmospheric hydrogen sulfide. Mercury even reacts with solid sulfur flakes, which are used in mercury spill kits to absorb mercury vapors. Mercury dissolves to form amalgams with gold, zinc, and many other metals.
Does mercury destroy gold?
Mercury dissolves many metals such as gold and silver to form amalgams.
Can mercury rust?
Mercury is a fairly unreactive metal and is highly resistant to corrosion. When heated to near its boiling point (346.72 deg C/675 deg F), mercury oxidizes in air, and mercuric oxide is formed.
Did you know about mercury?
Mercury is the smallest planet in the solar system. The diminutive planet is about 3,030 miles (4,876 kilometers) in diameter, making it about the size of the continental United States and only slightly bigger than Earth's moon. It's smaller than both Saturn's moon Titan and Jupiter's moon Ganymede.
What happens when mercury falls on gold?
Freddie Mercury may have had the golden voice, but real mercury, that endlessly entertaining and dangerous liquid metal, has the golden touch. That is, if it touches gold it will immediately break the lattice bonds of the precious metal and form an alloy in a process known as amalgamation.
How do you identify mercury?
The most commonly accepted methods of assessing mercury exposure are to test urine or blood. Both tests usually measure levels of total mercury (elemental, inorganic and organic). Elevated mercury in urine usually indicates exposure to an elemental or inorganic source of mercury, such as from a job that uses mercury.
Does Mercury have 10 moons?
Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons. In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have dozens of moons.
Why doesn't Mercury have any rings?
Sorry, Mercury doesn't have rings right now. ... Unfortunately, Mercury could never get rings like this. That's because it's too close to the Sun. The powerful solar winds blast out from the Sun, and would melt and destroy any icy rings around Mercury.
Does Mercury have ice?
Mercury is not alone in having ice on its surface, as water ice has also been discovered on the moon and on small worlds such as asteroids and comets. These locations may have variations in water deposition, however.
What is mercury famous for?
Mercury is the smallest and fastest planet in the solar system. It is also the closest planet to the sun. It is named after the Roman messenger god Mercury, the fastest Roman god. The planet Mercury was known by ancient people thousands of years ago.
