We’ve also recorded an entire episode of Astronomy Cast all about Mercury. A solar day on Mercury is as long as A. See no ads on this site, see our videos early, special bonus material, and much more. On Mars, a solar day lasts 24 hours, 39 minutes, and 35 seconds. And because of its virtually non-existence atmosphere and slow rotation, temperatures on its surface range from being extremely hot to extremely cold. Because of this proximity, Mercury has a rapid orbital period, which varies depending on where it is in its orbit. Trump's final act in office may be to veto the defense bill. Despite being the closest planet to our Sun, it is not the hottest (that honor goes to Venus). This work is licensed under a Creative Commons Attribution 4.0 International License. On average, its orbital velocity is 47.362 km/s (29.43 mi/s), which means it takes only 88 days to complete a single orbit of the Sun. Fauci's choice: 'Close the bars' and open schools. Required fields are marked *. by Colm Byrne on Wednesday, January 2nd, 2013. Join us at patreon.com/universetoday. Yes, as if Mercury weren’t strange enough, it turns out that a single day on Mercury lasts as long as two years! Actual rotation – Sidereal day on Mercury. But did you know that on Mercury you’d have a birthday every 88 days? It takes Mercury approximately 58.64 Earth days (1,408 hours) to rotate on its axis, also known as the sidereal time. Mercury is the closest planet to our Sun, ranging from 46,001,200 km at perihelion (closest to the Sun) to 69,816,900 km at aphelion (farthest). A day on Mercury is 58.646 Earth days or 1407.5 hours long while a day on Earth is 23.934 hours long. Mercury rotates very slowly compared to Earth so a day on Mercury is much longer than a day on Earth. For over 20 years, scientists believed that radar-bright images from Mercury’s northern polar regions might indicate the presence of water ice there. Mercury In this exercise, you will calculate the solar day for a person on Mercury. At the same time, … Mercury is the closest planet to our Sun, but it also has the most eccentric orbit (0.2056) of any of the Solar Planets. On Earth, a day is 23 hours and 56 minutes, but other planets and bodies rotate at different rates. the cycle of day and night. Listen here, Episode 49: Mercury. One day for Mercury is equal to 4222.6 Mercurian hours (or 1407.6 Earth hours). Mercury makes a full rotation around the sun in 88 Earth days, and it is the closest planet to the sun, which is a distance of 36 million miles. But, this then corrects itself and resumes its normal direction. one year on mercury is 80 days. 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! In fact, one day is actually as long as two years on Mercury. Related. On Mercury a day lasts 1,408 hours, and on Venus it lasts 5,832 hours. A mercury day (sidereal rotation period) is 58.646 earth days = 1407.5 hours. Equally unusual is the diurnal cycle on Mercury – i.e. In other words, a single day on Mercury lasts 1,408 hours - nearly 59 times longer than on Earth. It is daytime for one Mercurian year, and nighttime for one Mercurian year. Your email address will not be published. By Joseph Kiprop on May 20 2018 in Environment. Read this article to find out how long it takes all the planets in our solar system to make a trip around the Sun. one day on mercury is approximetly 10 secends. It takes about 175.97 Earth days from one sunrise to another, and this is due to the planet’s proximity to the sun and its high speed of orbiting around the sun. On Earth and Mars it’s very similar. If you’d like more info on Mercury, check out NASA’s Solar System Exploration Guide, and here’s a link to NASA’s MESSENGER Misson Page.

The Earth rotates once in 23 hours 56 minutes and 4 seconds. 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. The Moon, for example, spins on its axis once every 29.5 days. Sorry, your blog cannot share posts by email. Mercury rotates very slowly compared to Earth so a day on Mercury is much longer than a day on Earth. That's called a "sidereal day". The only places that are exempt to this day and night cycle are the polar regions. Mercury is the planet closest to the Sun and on Mercury the length of a day lasts 58 days, 15 hours on Earth. On Mercury, this would be about 58 Earth days, 15 hours and 30 minutes. 2/3 of a Mercurian year B. two Mercurian years C. one Mercurian year D. half a Mercurian year E. 24 hrs I'm thinking A but im not too sure A single day on Mercury lasts approximately 58 Earth days, 15 hours and 30 minutes. Just another oddity for a planet that likes to keep things really hot, really cold, and is really eccentric. Mercury rotates on its axis very slowly, while it orbits the sun quickly. The extra 2.2 days is the time for the Moon to catch up in its rotation. Here’s How Long is Day on the Other Planets?, Which Planet has the Longest Day?, How Long is a Day on Venus?, How Long is a Day on Earth?, How Long is a Day on the Moon?, How Long is a Day on Mars?, How Long is a Day on Jupiter?, How Long is a Day on Saturn?, How Long is a Day on Uranus?, How Long is a Day on Neptune?, and How Long is a Day on Pluto? Equally unusual is the diurnal cycle on Mercury – i.e. A single year lasts only 88 days on Mercury, but thanks again to its slow rotation, a day lasts twice as long! A year on Mercury is about 88 Earth days long. Your email address will not be published. Eclipsewise 2019 transit of mercury mercury s year length is only 88 days mercury colonization today is not 24 hours long what makes the earth spin on its axis How Long Is Day On Mercury Universe TodayWhich Pla Has The Longest Day Plas TodayHow Long Is A Year On Other Plas UniverseHow Long Is One… Read More » Save my name, email, and website in this browser for the next time I comment. That means future lunar inhabitants will have to get used to a sunlight "day" that lasts for about 14 Earth days and a … Click to share on Facebook (Opens in new window), Click to share on Pocket (Opens in new window), Click to share on Twitter (Opens in new window), Click to share on LinkedIn (Opens in new window), Click to share on Tumblr (Opens in new window), Click to share on Pinterest (Opens in new window), Click to share on Reddit (Opens in new window), Click to email this to a friend (Opens in new window), Creative Commons Attribution 4.0 International License. Temperatures in these craters are also cool enough that significant concentrations of water ice can exist in stable form. A single year lasts only 88 days on Mercury, but thanks again to its slow rotation, a day lasts twice as long! No-one on Mercury could claim there are not enough hours in the day. If every day was as long as today, a leap second would have to be added every 1998.80 days. It gets to a point in its orbit when the speed of its orbital velocity is the same as its angular rotational velocity. Mercury is the planet closest to the Sun and on Mercury the length of a day lasts 58 days, 15 hours on Earth. A day on Mercury is 58.646 Earth days or 1407.5 hours long while a day on Earth is 23.934 hours long. Due to its rapid orbital velocity and slow sidereal rotation, a Solar Day on Mercury (the time it takes for the Sun to return to the same place in the sky) is actually 176 days.
