A day in Mercury is twice as long as a year in Mercury. Average Day Lengths & Leap Seconds In rare cases, a day can also be shorter than 24 hours. Mercury rotates on its axis very slowly, while it orbits the sun quickly. The Guide to Space is a series of space and astronomy poddcasts by Fraser Cain, publisher of Universe Today, Episode 700: Interview: Wallace Arthur and the Biological Universe. In that respect, the ratio of days to years on Mercury is actually 1:2. Saturn takes 11 hours, Uranus takes 17 hours, and Neptune takes 16 hours. Elemental mercury:People may be exposed when they breathe air containing elemental mercury vapors. It rotates very slowly on its axis. Temperatures in these craters are also cool enough that significant concentrations of water ice can exist in stable form. The axial tilt of Mercury is 0.027 degrees. ... Mercury: One year on planet Mercury takes just 87.97 earth days. Wednesdays are a day of discovery, business and practical matters. Shelley Moore is a journalist and award-winning short-story writer. It is small and rocky. We’ve written many articles about Mercury for Universe Today. Mercury is a small planet with an equatorial diameter of 4,879 kilometers. In other words, a single day on Mercury lasts 1,408 hours – nearly 59 times longer than on Earth. That means that if you could stand on the surface of Mercury, it would take a staggering 176 Earth days for the Sun to rise, set and rise again to the same place in the sky just once! Post was not sent - check your email addresses! While this might lead some to conclude that a single day on Mercury is about 58 Earth days – thus making the length of a day and year correspond to the same 3:2 ratio – this would be inaccurate. It can be as cold as -290 degrees Fahrenheit (-179 degrees Celsius) on Mercury at night. Based on data obtained by these radar measurements, Mercury is now known to be in 3:2 orbital resonance with the Sun. A century ago, the average day was about 1.7 milliseconds shorter than today. A day in Mercury is twice as long as a year in Mercury. Indeed, the length of its day was not determined until the 1960s, and Mercury’s nearness to the Sun gave scientists bound to Earth many observational hurdles, which were overcome only by the Messenger (Mercury Surface, Space Environment, Geochemistry, and Ranging) probe. Because of this proximity, Mercury has a rapid orbital period, which varies depending on where it is in its orbit. In November of 2012, NASA’s MESSENGER probe examined the northern polar region using its neutron spectrometer and laser altimeter and confirmed the presence of both water ice and organic molecules. A 100 pound person would weigh only 38 pounds on Mercury. One Mercury solar day (one full day-night cycle) equals 176 Earth days—just over two years on Mercury. This means that if you are 15 years old on Earth you would be 62 years old in Mercury years. Mercury is one of the most unusual planets in our Solar System, at least by the standards of us privileged Earthlings. She has a Bachelor of Science in psychology. This is the smallest axial tilt in the solar system with Jupiter coming in at second. https://www.amazon.com/Universe-Today-Ultimate-Viewing-Cosmos/dp/1624145442/, Audio Podcast version: Inside Mercury.

On Mercury a day lasts 1,408 hours, and on Venus it lasts 5,832 hours. It takes 88 days for the planets to orbit the Sun so a year is quit short compared to 365 days on Earth. In fact, one day is actually as long as two years on Mercury. Number Four: A Day on Mercury. Mercury rotates one-and-a-half times during each orbit around the Sun. Naturally, it moves fastest when it is at its closest to the Sun, and slowest when it is farthest. It takes about 176 Earth days for Mercury to rotate on its axis (from sunrise to sunrise), while Earth takes only 24 hours. Equally unusual is the diurnal cycle on Mercury – i.e. Mercury rotates on its axis very slowly, while it orbits the sun quickly. This means that while its average distance (semi-major axis) from the Sun is 57,909,050 km (35,983,015 mi) or 0.387 AUs, this ranges considerably – from 46,001,200 km (2,8583,820 mi) at perihelion (closet) to 69,816,900 km (43,382,210  mi) at aphelion (farthest). If Earth were the size of a nickel, Mercury would be about as big as a blueberry. At it’s current rotational velocity – 3.026 m/s, or 10.892 km/h (6.77 mph) – it takes Mercury 58.646 days to complete a single rotation on its axis.
