There are 86400 seconds.


What is Mars length of days?

solar day is 24 hours 39 minutes 35.244 seconds and Mars rotates every 24.62296 earth hours


What planet has a day about as long as earth?

Mars. A "day" on Mars - which astronomers working with the Lunar Rovers call a "sol" - is about 24 hours 39 minutes 35 seconds. That's a "solar day". The "sidereal day" is a couple of minutes shorter.


How long is one day on Mars?

A day on Mars (the time it takes to rotate on its axis) is 24.62 hours, just slightly longer than a day on Earth. A year on Mars (the time it takes to go around the Sun) is 686.97 days, almost 2 of our Earth years. A day on Mars is 24 hours, 39 minutes and 35 seconds; amazingly similar to a day on Earth. This is just one of the reasons that space enthusiasts think that Mars might make a good planet for colonization. 199995 earth days


Length of one day on the planets?

Definition Day:One Earth day is 24 hours or 86,400 seconds.That is a legal and standardized definition.It turns out there are several others which are needed to be sure of the answer of this question.Astronomical Day:If someone asks how long one day is, then the answer depends on whether one defines the day according to how long it takes the Sun to return to its position in the sky or whether it refers to how long the stars take to return to their apparent position in the sky. Normally, the question refers to the Solar day.1. Solar Day: A mean solar day is about 86,400.002 SI seconds.Originally, a day and the definition of hours and seconds was defined according to the solar day. The solar day is the time it takes the sun to go from its noon position in the sky to the same position again. That actually changes by a few seconds during the course of a year. Over a year, year to year, it averages to nearly the exact same time and at the moment it averages 2 thousandths of a second longer than it did when they made the original definition.2. Rotation Period (also called the stellar day or the similar idea, the sidereal day):The rotation period is the time it takes for the planet to complete one rotation relative to the fixed stars (not relative to the Sun). For Earth the rotation period is 0.99726968 days or 23 hours 56 minutes and 4.100 seconds. For Earth (the stellar day and the sidereal day are nearly of the same) this is about 3 minutes 56 seconds shorter than the solar day. As a consequence, the Earth rotates about 366 times a year.
