How would you describe mercury?

Answer 1

Mercury, the innermost planet of the solar system, is a little bigger than the Earth's Moon. The surface of the planet is covered with craters, like the Moon, but temperatures there can reach over 800oF because Mercury is so close to the Sun and rotates so slowly. Scientists believe that the interior structure of Mercury includes a metallic core, an intermediate rocky layer, and a thin brittle crust. The composition of Mercury is probably high in iron, although surface features indicate that volcanic activity once existed at the surface. There is little evidence of motions near the surface of the planet now, although at earlier times during Mercury's evolution the surface was much more active. We know relatively little about Mercury, compared to most of the other planets, because it is relatively difficult to see and only one spacecraft has studied the planet.

Answer 2

Being the closest planet to the sun, Mercury has a pretty hot surface, however not as hot as Venus. After the demotion of Pluto to a dwarf planet, Mercury is now the smallest planet in the solar system, with a diameter of only 4879.4 km. Albeit its small size, it has the second largest density in the solar system, at 5.4 g/cm3. The size also contributes to its small gravity, only about 38% of that on Earth.

As for orbit and rotation, Mercury takes 88 days to complete one revolution around the Sun, and yet it takes almost 59 days to turn once on its axis.

Answer 3

I am not sure if you mean by Mercury the element or the planet.

However, if you mean the element, then:

• Mercury is a chemical element with the symbol Hgand atomic number 80.
• Mercury is the only metal that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is bromine
• Its freezing point of −38.83 °C and boiling point of 356.73 °C,
• Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide).
• The red pigment vermilion, a pure form of mercuric sulfide, is mostly obtained by reaction of mercury (produced by reduction from cinnabar) with sulfur.
• Mercury is used in thermometers, barometers, manometers, float valves, mercury switches, mercury relays, fluorescent lamps and other devices .
• It remains in use in scientific research applications and in amalgam material for dental restoration in some locales.
• It is used in lighting: electricity passed through mercury vapor in a fluorescent lamp produces short-wave ultraviolet light which then causes the phosphor in the tube to fluoresce, making visible light.

If you mean Mercury the planet, then:

• Mercury is the smallest and closest to the Sun of the eight planets in the Solar System
• Its orbital period of about 88 Earth days.
• Seen from the Earth, it appears to move around its orbit in about 116 days, which is much faster than any other planet.
• Because it has almost no atmosphere to retain heat, Mercury's surface experiences the greatest temperature variation of all the planets, ranging from −173 °C at night to 427 °C during the day at some equatorial regions.
• Mercury's surface is heavily cratered and similar in appearance to the Moon, indicating that it has been geologically inactive for billions of years.
• Mercury does not experience seasons in the same way as most other planets, such as the Earth.

Answer 4

Mercury is a silver-colored liquid metal that is the only metal that is liquid at room temperature. It is a heavy element with high toxicity and is commonly used in thermometers and other scientific equipment. Mercury can easily evaporate into a toxic vapor, making proper handling and disposal important.

Answer 5

Mercury is similar to the moon. It is covered in craters, has a very thin atmosphere. Because of the small atmosphere, Mercury has the biggest temperature change known.

Answer 6

Mercury is the only liquid metal at room temperature.

Answer 7

Small, sun-baked, dead and highly crater impacted world nearest the sun in our solar system.
