Mars sol. Sol (borrowed from the Latin word for sun) is a solar day on Mars; that is, a Mars-day. A sol is the apparent interval between two successive returns of the Sun to the same meridian (sundial time) as seen by an observer on Mars. It is one of several units for timekeeping on Mars. A sol is slightly longer than an Earth day.
Mars' Calendar. Time on Mars is easily divided into days based on its rotation rate and years based on its orbit. Sols, or Martian solar days, are only 39 minutes and 35 seconds longer than Earth days, and there are 668 sols (687 Earth days) in a Martian year.
As Mars orbits the Sun, it completes one rotation every 24.6 hours, which is very similar to one day on Earth (23.9 hours). Martian days are called sols – short for "solar day." A year on Mars lasts 669.6 sols, which is the same as 687 Earth days.
Definition of year and seasons. The length of time for Mars to complete one orbit around the Sun in respect to the stars, its sidereal year, is about 686.98 Earth solar days (≈ 1.88 Earth years), or 668.5991 sols. Because of the eccentricity of Mars' orbit, the seasons are not of equal length.

We’re very accustomed to the daily cycle on our planet – the Earth spins anticlockwise on its axis, beginning the day with the Sun rising in the east and eventually setting in the west. That takes us into night and finally to a new day with the Sun rising once again. However the length of a day can be defined in two ways – a sidereal day and a sola...
The time it takes for a planet to spin once so that the stars appear in the same position again in the night sky is known as a sidereal day. On the Earth that is 23 hours 56 minutes and 4 seconds. Although astronomers sometimes use the sidereal day as a passage of time, in our everyday lives we’re more familiar with the idea of a solar day.
This is the amount of time it takes for a planet to spin on its axis so that the Sun appears in the same position in the daytime sky (typically when the Sun is on the local meridian). For the Earth a solar day is 24 hours long on average. A solar day is longer than a sidereal day because not only is the Earth spinning on its axis (anticlockwise) bu...
Mars is a planet with a very similar daily cycle to the Earth. Its sidereal day is 24 hours, 37 minutes and 22 seconds, and its solar day 24 hours, 39 minutes and 35 seconds. A Martian day (referred to as “sol”) is therefore approximately 40 minutes longer than a day on Earth. It wouldn’t be too difficult to accustom ourselves to the cycle of a Mar...
The average temperature on Mars is -60 degrees Centigrade. Seasonal changes take the Martian temperature from 20 degrees C at the equator during summer down to -125 degrees C at the poles in winter. With the atmosphere of Mars being 100 times thinner than on the Earth, daily temperature fluctuations are also quite extreme. With no ‘thermal blanket’...
Earth isn’t the only planet with extreme weather – in fact the other planets have some extremely riotous weather. Mars has 'dust devils' purging over its surface. Although most don’t pose a threat, they are comparable to tornadoes – vertical, rapidly rotating columns of air. Solar heat creates convection currents which drive the winds on Mars. Due ...
May 15, 2023 · A Mars solar day has a mean period of 24 hours 39 minutes 35.244 seconds, and is customarily referred to as a "sol" in order to distinguish this from the roughly 3% shorter solar day on Earth. The Mars sidereal day, as measured with respect to the fixed stars, is 24h 37m 22.663s, as compared with 23h 56m 04.0905s for Earth.

Nov 8, 2024 · Option 1: A Paragraph. We can write a paragraph about how long days last on other planets. On Mercury a day lasts 1,408 hours, and on Venus it lasts 5,832 hours. On Earth and Mars it’s very similar. Earth takes 24 hours to complete one spin, and Mars takes 25 hours. The gas giants rotate really fast.
