### How many Earth hours is in one Mars day?

The simple answer is "just over 24 hours". More details: A day on Mars is 24 hours, 39 minutes and 35 seconds That's the "solar day". The rotation period or "sidereal day" is a couple of minutes less. For comparison, on Earth the solar day is 24 hours and the sidereal day is about 23 hours and 56 minutes.

### How many earth hours are in 6 days on mercury?

There are two main definitions of "day" : "Sidereal day" and "Solar day". On Mercury the sidereal day is about 58.6 Earth days. That's about 1406.4 hours. The solar day is about 176 Earth days That's about 4224 hours. So, the answer is 1406.4 x 6 = 8438 hours, approximately. or 4224 x 6 = 25344 hours, approximately.

### What is the length of a day for all of the planet to planet?

There are two main definitions of "day" for a planet: 1) Sidereal day. That's the time taken to rotate once. 2) Solar day. That's the time taken for the Sun to complete one apparent journey around the sky. Usually it's given as the "mean solar day", which is the average value. The solar day depends on the planet's orbital motion, as well as its rotation. Here are the details, with slight approximations: Mercury : sidereal…

### How long earth hours is 1 day on a different planet?

The length of a "sidereal" day (rotation period) is different on every planet. These are the approximate times: Mercury 58.7 earth days, (multiply by 24 to get the day length in hours), Venus 243 earth days, Earth 23 hours 56 minutes, Mars 24.6 hours, Jupiter 9.84 hours, Saturn 10.2 hours, Uranus 17.9 hours, Neptune 16.1 hours. The length of the "solar" days are very similar, except for Mercury and Venus. For example Earth's solar day…

### How many hours makes a year?

~8766 mean solar hours or 8760 hours based on calendar hours. Notes: 1. "~" = "approximately". 2. Earth's orbital time around the sun = 365.256363 mean solar days per year. 3. Earth's axial rotation time = 86400.002 mean solar seconds per day 4. 86400.002 / 3600 * 365.256363 = ~8766.2 hours 5. Alternatively, if you assume 24 hours/day & 365 days per year, the answer would be: 24 * 365 = 8760 hours in a…

### How many hours are in a day on earth?

There are 24 hours in a day. That's the " solar day". It's what most people understand by the word "day". Technically it's the "mean solar day" because it's the average time, allowing for natural variations, mainly in the Earth's orbit around the Sun. There are 23 hours and 56 minutes in a "sidereal day". That's the time the Earth takes to rotate once. The extra 4 minutes are needed to allow for the Earth's…

### How many hours does it take for the earth to rotate?

24 hours (approximately). The "solar day" is exactly 24 hours, but it actually takes about 23 hours and 56 minutes for the Earth to rotate once. The extra four minutes are needed to allow for the change in position of the Sun in the sky due to the Earth orbiting the Sun. Answer: While the basis for the hour is the length of the "solar day" split into 24 parts (so you'd think the day…

### What is the length of a Venus day in Earth hours?

It depends what you mean by "day". Venus rotates in about 243 Earth days. This is called a sidereal day. So that's about 243 x 24 Earth hours. However the "solar day" on Venus is about 117 Earth days. So that's about 117 x 24 Earth hours. The solar day is 24 hours on Earth. It's how long the Sun takes to complete one journey through the sky from noon till noon. The Earth's rotation…
