After the discovery, MESSENGER continued to study the polar ice deposits over its extended mission. NY 10036. Mercury rotates slowly and has a thin atmosphere, and consequently, the night-side temperature can be more than 1,000 degrees Fahrenheit lower than the day-side temperature shown on the diagram. This does not, however, mean that three days last the same as two years on Mercury. Its surface temperature can reach 801 Fahrenheit during the day (because it is so close to the Sun) and can drop to -279 Fahrenheit at night (because there is no atmosphere to trap the … Since Mercury has hardly any atmosphere, it does not have weather like storms, clouds, winds or rain. What is the Average Surface Temperature of Uranus? Mercury's low mass and proximity to the sun keep it from having anything but the thinnest of atmospheres, and this is the reason it must pass on being the hottest planet. Overall, Mercury experiences considerable variations in temperatures, ranging from the extremely hot to the extremely cold. (This is hot enough to melt lead!) But strangely enough, it is not. These variations are relatively long-lived. Weather Underground provides local & long-range weather forecasts, weatherreports, maps & tropical weather conditions for the Mercury area. (Image: © NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington). Mercury Weather Forecasts. Hi, I’m Shannon Kohlitz, as in the person credited for the graphic of the MESSENGER spacecraft traveling around Mercury. Mercury thermometers can be used to determine body, liquid, and vapor temperature. There was a problem. Space is part of Future US Inc, an international media group and leading digital publisher. And if you have a news tip, correction or comment, let us know at: community@space.com. Little wonder then why there is no life on the planet (at least, that we know about!) Mercury is a planet of extremes. Mercury is the closest planet to the sun. In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. We have written many interesting articles about the average surface temperatures of the planets. But although it boasts the most widely varying temperatures in the solar system, it is not the hottest planet How is this possible? Whereas the side facing the Sun experiences temperatures hot enough to melt lead, the darkened areas are cold enough to freeze water. The hottest planet, incidentally, is Venus, the second body from the sun. It boils at 356.9 °C (674 °F). "The buried layer has a hydrogen content consistent with nearly pure water ice.". I merely animated it. A digital thermometer is used to take an oral temperature. Whereas the side that faces the Sun can reach temperatures of up to 700 K (427° C; 800 °F), the side in shadow dips down to 100 K (-173° C: -279 °F). Thank you for signing up to Space. The planet also has the lowest axial tilt of any planet in the Solar System – approximately 0.027° compared to Jupiter’s 3.1°, (the second smallest). The average temperature on Mercury is a balmy 354 degrees F. In addition, since Mercury has virtually no atmosphere to scatter light, the sky would be black, even though the Sun's disk itself would be over twice as large as what we observe from the Earth. © In contrast, the chilly night side can get as cold as minus 290 F (minus 180 C). From this distance, it takes sunlight 3.2 minutes to trave… Get breaking space news and the latest updates on rocket launches, skywatching events and more! If you’d like more information on Mercury, check out NASA’s Solar System Exploration Guide, and here’s a link to NASA’s MESSENGER Misson Page. In fact, its high eccentricity and slow rotation mean that it takes 176 Earth days for the Sun to return to the same place in the sky (aka. According to NASA, the tiny world suffers the most extreme temperature range of any other planet in the solar system. If Earth were the size of a nickel, Mercury would be about as big as a blueberry. Mercury has a unique electron configuration which strongly resists removal of an electron, making it behave similarly to noble gas elements. If that sounds familiar, it's because Uranus is about the same temperature. Venus has a thick atmosphere that blankets the planet, keeping its temperature at an average of 864 F (462 C). Delhi Temperature: Normally, the Safdarjung Observatory records a minimum of 15 to 16 degrees Celsius in the first week of November. Mercury conducts electricity and is used to make silent, position dependent switches. it contains mercury, which is a dangerous element. An atmosphere helps to cloak a planet, keeping heat from leaking into space.

On Earth, seasonal temperature shifts are caused by the tilt of the planet's axis. But perhaps someday, human beings may live there, sheltered in the cratered regions and using the water ice to create a habitat. Mercury can be used to make thermometers, barometers and other scientific instruments. https://www.youtube.com/channel/UCUHI67dh9jEO2rvK–MdCSg, Support us at: https://www.patreon.com/universetoday There are thought to be craters at the south pole as well, where temperatures are similarly cold enough to sustain water in ice form. "The neutron data indicates that Mercury's radar-bright polar deposits contain, on average, a hydrogen-rich layer more than tens of centimeters thick beneath a surficial layer 10 to 20 centimeters thick that is less rich in hydrogen," said MESSENGER participating scientist David Lawrence at the Johns Hopkins University Applied Physics Laboratory. There may be ice on the top and bottom of Mercury. Because of this, its distance from the Sun varies between 46 million km (29 million mi) at its closest (perihelion) to 70 million km (43 million mi) at its farthest (aphelion).

Please refresh the page and try again. Wallace Arthur is an evolutionary biologist and emeritus professor of Zoology at the National University of Ireland, Galway. What kind of thermometer is used to take an oral temperature? That allows Mercury, the closest planet to the sun, to hang onto ice at its surface. These trace gases have a combined atmospheric pressure of about 10-14 bar (one-quadrillionth of Earth’s atmospheric pressure). https://www.universetoday.com/newsletter, Weekly Space Hangout: Visit our corporate site. We have also recorded a whole episode of Astronomy Cast that’s just about planet Mercury. https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/, Astronomy Cast: As a result of this and its high eccentricity, the planet experiences considerable variations in temperature between its light side and dark side. Follow us on Twitter: @universetoday Not only that, but Mercury is also cold enough in … a solar day), which means that one day is twice as long as a single year on Mercury. Mercury Facts: Mercury orbits the Sun faster than any other planet. Follow Nola Taylor Redd on Twitter @NolaTRedd Facebook or Google+. The day side of the planet reaches temperatures of up to 800 degrees Fahrenheit (427 degrees Celsius). Threat of mercury spills and leak. What is the Average Surface Temperature of Jupiter? The temperature increase of the mercury is: {eq}\Delta T = 110^\circ {\rm{C}} {/eq} Write the expression for the energy required to raise the temperature of the mercury. If the Southern Hemisphere is closer to the sun than its northern counterpart, it experiences spring and summer instead of autumn and winter. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Join our Space Forums to keep talking space on the latest missions, night sky and more! By refining the imaging, MESSENGER captured images of the deposits on the surface.

However, further studies revealed that the planet spins very slowly — only three times every two Mercury years, or once every 60 Earth days. Future US, Inc. 11 West 42nd Street, 15th Floor, can be used for oral, rectal, and axillary or groin temperatures. This means that Mercury has a spin-orbit resonance of 3:2, which means that it completes three rotations on its axis for every two orbits around the Sun. A normal temperature is usually lower in the morning and increases during the day. Before the sunrise the temperature on the surface of Mercury is as low as 100 K (-170 °C) and by noon the temperature on the surface of Mercury rises to about 700 K (400 °C). Scientists once thought that Mercury kept a single side perpetually facing the sun, in a condition known as tidal locking. Because it lacks a viable atmosphere, Mercury has no way to retain the heat from the Sun. It is used in older thermometers, fluorescent light bulbs and … This collection of mercury facts includes atomic data, the electron configuration, chemical and physical properties, and history of the element. However, Mercury has the least circular, most eccentric orbit of all the planets. And with an average orbital velocity of 47.362 km/s (29.429 mi/s), it takes Mercury a total 87.969 Earth days to complete a single orbit around the Sun. Follow us at @Spacedotcom, Facebook or Google+. It melts at 234.3 K. Convert this melting point to degrees Celsius. The planet has an average temperature of 332 F (167 C).
