Mercury is only about one-third the size of the Earth. On Earth, seasonal temperature shifts are caused by the tilt of the planet's axis. https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/, Astronomy Cast: It is smaller than any other planet. These variations are relatively long-lived. Please refresh the page and try again. 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).

And More…, Episode 691: Interview: Seth Shostak from the SETI Institute, Creative Commons Attribution 4.0 International License. Since Mercury is the closest planet to the Sun, spins slowly, and does not have much of an atmosphere to trap heat, its temperature varies greatly. Mercury is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications. NY 10036. Spain and Italy produce about half of the world's supply of Mercury. Chad Weber – [email protected], Support Universe Today podcasts with Fraser Cain. Mercury's temperatures can go between -279 Fahrenheit (-173 Celsius) at night to 801 Fahrenheit (427 Celsius) during the day. The normal oral temperature for older persons is 98.2° F (36.8° C). We’ll certainly straighten that out, and thanks for letting us know , Join our 836 patrons! The average temperature on Neptune is about -360℉. Mercury is the only metal that exists as a liquid at room temperature. It has an extremely eccentric orbit, an extremely thin-atmosphere, and experiences extremely hot and cold surface temperatures. What is the Average Surface Temperature of Mars? Mercury has the most eccentric orbit of any planet in the Solar System (0.205). There are thought to be craters at the south pole as well, where temperatures are similarly cold enough to sustain water in ice form. There may be ice on the top and bottom of Mercury. 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. But strangely enough, it is not. Scientists once thought that Mercury kept a single side perpetually facing the sun, in a condition known as tidal locking. A digital thermometer is used to take an oral temperature. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. You will receive a verification email shortly. Mercury can be used to make thermometers, barometers and other scientific instruments. Delhi Temperature: Normally, the Safdarjung Observatory records a minimum of 15 to 16 degrees Celsius in the first week of November. NASA.gov brings you the latest images, videos and news from America's space agency. All of this arises from the fact that Mercury has an extremely thin atmosphere, as well as the nature of its orbit. Despite its extreme highs in temperature, the existence of water ice and even organic molecules has been confirmed on Mercury’s surface, specifically in the cratered northern polar region. From this distance, it takes sunlight 3.2 minutes to trave… a solar day), which means that one day is twice as long as a single year on Mercury.

Wallace Arthur is an evolutionary biologist and emeritus professor of Zoology at the National University of Ireland, Galway. The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam (1714). https://www.youtube.com/playlist?list=PLbJ42wpShvmkjd428BcHcCEVWOjv7cJ1G, Weekly email newsletter: Mercury is … One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. Mercury Weather Forecasts. Since Mercury has hardly any atmosphere, it does not have weather like storms, clouds, winds or rain.
