How Long Does It Take For The Sun To Rise

How Long Is One Mean solar day on Other Planets?

The Short Answer:

Planet	Day Length
Mercury	1,408 hours
Venus	five,832 hours
Earth	24 hours
Mars	25 hours
Jupiter	ten hours
Saturn	11 hours
Uranus	17 hours
Neptune	xvi hours

When yous retrieve of a twenty-four hour period, you normally think of one cycle of daytime to dark. That is called a solar 24-hour interval. On Globe, a solar mean solar day is effectually 24 hours. However, Globe's orbit is elliptical, meaning information technology'south not a perfect circle. That means some solar days on World are a few minutes longer than 24 hours and some are a few minutes shorter.

Another mode to measure a solar day is to count the amount of time information technology takes for a planet to completely spin around and brand ane full rotation. This is chosen a sidereal day. On Earth, a sidereal twenty-four hours is almost exactly 23 hours and 56 minutes.

We know how long an Earth day is, simply how about the other planets in our solar organisation? How long does information technology have for those planets to spin 1 full rotation? And what is the best way to show the respond to this question?

Permit's await at a few options.

Option 1: A Paragraph

We can write a paragraph about how long days final on other planets.

On Mercury a 24-hour interval lasts ane,408 hours, and on Venus it lasts 5,832 hours. On Globe and Mars it'south very like. Earth takes 24 hours to complete 1 spin, and Mars takes 25 hours. The gas giants rotate really fast. Jupiter takes but 10 hours to complete one rotation. Saturn takes 11 hours, Uranus takes 17 hours, and Neptune takes 16 hours.

Reading that paragraph took a while, and it's hard to find all the numbers. Permit's encounter how it looks if we put it in a table.

Option ii: A Table

Planet	24-hour interval Length
Mercury	1,408 hours
Venus	v,832 hours
Earth	24 hours
Mars	25 hours
Jupiter	10 hours
Saturn	xi hours
Uranus	17 hours
Neptune	16 hours

That'south a little fleck improve. We can wait up and downwardly at the numbers and can compare them more than easily. But wouldn't it be squeamish if nosotros could see how big those differences are?

Allow'southward make a graph with these numbers!

Selection three: A Graph

To start, make a number line that starts at 0 and goes to the highest number you need to include. This first graph will merely have Earth, Mars, Jupiter, Saturn, Uranus, and Neptune on it. Nosotros'll save Mercury and Venus for later. You'll see why in a infinitesimal.

The longest day among those planets is 25 hours. That means our number line volition become up to 25.

Label the number line then you remember it represents hours. And write what information the graph will have at the top.

Along the bottom, write the names of the planets.

Make a dot in a higher place the name of the planet next to the number of hours its day takes.

Our graph is coming together!

What do we exercise now? Color in the area below the dot to make a bar graph.

At present we can easily see which planet has the longest day, the shortest twenty-four hour period, and everything in between. This is much easier than reading a list of numbers, don't you recollect?

But what do nosotros do about Mercury and Venus? Their days are thousands of hours long. How practise we brand a graph for those?

Nosotros make a number line, but instead of numbers 1, 2, iii… nosotros volition use 1,000, 2,000, 3,000…

Make a number line that goes all the style up to 6,000. Along the bottom, write Mercury and Venus. Above Mercury, mark a dot a picayune less than halfway betwixt 1,000 and ii,000. It'south not going to be perfect, but that's okay. At present make a dot a little under half-dozen,000 for Venus.

Practise you lot recall we can include World, Mars, Jupiter, Saturn, Uranus, and Neptune on here? Their dots would be so close to 0 it would be hard to tell the difference between them. Graphs piece of work best when the numbers are like in size, usually with the same number of digits.

Now that you lot know how to brand a graph, you tin can bear witness all kinds of data this fashion. Y'all can graph the time it takes to get to schoolhouse each 24-hour interval, the number of pieces of pizza your friends tin can swallow, and how many people like the color blue or green. Go on and get graphing!
