When and where to look. Currently, Mercury is visible about 35 to 40 minutes after sunset, very near to the horizon, about 25 degrees south of due west. Your clenched fist held at arm's length measures roughly 10 degrees, so approximately 2.5 "fists" to the left of due west, along the horizon, will bring you to Mercury
Habitability. There may be scientific support, based on studies reported in March 2020, for considering that parts of the planet Mercury may have been habitable, and perhaps that life forms, albeit likely primitive microorganisms, may have existed on the planet.
Mercury is rarely found in nature as the pure, liquid metal, but rather within compounds and inorganic salts. Elemental mercury is a shiny, silver-white metal that is a liquid at room temperature and is traditionally used in thermometers and some electrical switches.
What does Mercury look like? Here you can see that Mercury is a light grey color. This is Mercury's northern horizon as seen by the MESSENGER spacecraft during its third flyby.
June 8: Moon and Saturn
A beautiful trio highlights the after-midnight sky tonight: the Moon and the planets Jupiter and Saturn. Jupiter is the brighter of the two worlds, but Saturn stands closer to the Moon.Mercury, the innermost planet, orbits the sun inside Earth's orbit and is often lost in the glare of the sun. But, at opportune times – like now, for the Northern Hemisphere – you can see Mercury fairly easily, if you go outside and look west after sunset.
From space, Earth looks like a blue marble with white swirls. Some parts are brown, yellow, green and white. The blue part is water. Water covers most of Earth.
Right now, Mercury is a nearly full disk, which is why it starts off appearing so bright. Mercury reaches its greatest elongation, 22 degrees to the east of the Sun, on May 14. Shining at magnitude +0.4 (as bright as the star Procyon in Canis Minor), it will set nearly two hours after the Sun.
Mercury is a terrestrial planet having three main layers: a core, mantle and crust. Mercury's crust has no tectonic plates and its iron core is enormous, making up 85% of the planets radius while Earth's inner and outer core, account for about 55%.
Mercury looks pretty, in its shiny, fast-moving liquid form, but don't touch! It can be extremely poisonous to humans. The symbol Hg that mercury is known by comes from its Greek name, hydrargyrum, which means "liquid silver" — to reflect its shiny surface. Mercury is a very toxic element.
Mercury is one of the five classical planets visible with the naked eye and is named after the swift-footed Roman messenger god. It is not known exactly when the planet was first discovered - although it was first observed through telescopes in the seventeenth century by astronomers Galileo Galilei and Thomas Harriot.

In spite of its proximity to the Sun, Mercury may have surface ice, since temperatures near the poles are constantly below freezing point: On the polar plains, the temperature does not rise above −106 °C. However, the evidence for ice on Mercury is not definitive.
How Did Mercury Get Its Name? The Romans believed that gods and goddesses were in charge of everything on Earth. Mercury is named after the messenger for their gods. The Roman Mercury had wings on his helmet and shoes.
Where is Mercury located?
RA 7h 1m 18s | Dec +20° 6′ 34″
It has a solid surface that is covered with craters. It has no atmosphere, and it doesn't have any moons. Mercury likes to keep things simple. This small planet spins around slowly compared to Earth, so one day lasts a long time.
Scientists have found that the planet has been shrinking, based on deformations in the surface called lobate scarps and wrinkle ridges. They say the world is getting smaller -- and in Mercury's case it's literally true.
The day side of the planet reaches temperatures of up to 800 degrees Fahrenheit (427 degrees Celsius). In contrast, the chilly night side can get as cold as minus 290 F (minus 180 C). The planet has an average temperature of 332 F (167 C). These variations are relatively long-lived.
Because it is so close to the sun, it can be very hot. On its sunny side, Mercury can reach a scorching 800 degrees Fahrenheit! (But Mercury is not the hottest planet in the solar system. On its dark side, Mercury gets very cold because it has almost no atmosphere to hold in heat and keep the surface warm.
Inside Planet Mercury (Infographic) Mercury is the closest planet to the Sun in Earth's solar system, but has no moons and no substantial atmosphere. Since it has no significant atmosphere to stop impacts, the planet is pockmarked with craters.
Mercury is hot. If we're being quantitative, it's actually extremely hot! As the closest planet to the Sun, it completes an orbit in just 88 Earth-days, achieving a maximum temperature during the day of a whopping 700 Kelvin (427 °C / 800 °F) at its hottest, equatorial locations.
Mercury and Venus
Neither of them has a moon. Because Mercury is so close to the Sun and its gravity, it wouldn't be able to hold on to its own moon. Any moon would most likely crash into Mercury or maybe go into orbit around the Sun and eventually get pulled into it.Neither of them has a moon. Because Mercury is so close to the Sun and its gravity, it wouldn't be able to hold on to its own moon. Any moon would most likely crash into Mercury or maybe go into orbit around the Sun and eventually get pulled into it. Why Venus doesn't have a moon is a mystery for scientists to solve.
What is the size of Mercury?
The same can probably be said of Mercury, the best planet in the solar system (other than Earth). It lacks a real atmosphere, so there's nothing preventing asteroids from hitting the surface, and the planet has billions of years worth of craters to show for it.
Mercury Facts
Mercury is one of the five planets known to the ancients. They called these planets "wandering stars." Mercury may be seen as an evening "star" near where the sun has set, or as a morning "star" near where the sun will rise. The planet is named for Mercury, the Roman messenger of the gods.The second largest planet in the solar system, Saturn is a "gas giant" composed primarily of hydrogen and helium. But it's best known for the bright, beautiful rings that circle its equator. The rings are made up of countless particles of ice and rock that each orbit Saturn independently.
Mercury is the smallest and innermost planet in the Solar System. Its orbit around the Sun takes 87.97 days, the shortest of all the planets in the Solar System. It is named after the Roman deity Mercury, the messenger of the gods.
The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth's Moon. But Mercury is the fastest planet, zipping around the Sun every 88 Earth days. Mercury is appropriately named for the swiftest of the ancient Roman gods.
