## What is the orbital period of each planet?

The Days (And Years) Of Our Lives

Planet Rotation Period Revolution Period
Mars 1.03 days 1.88 years
Jupiter 0.41 days 11.86 years
Saturn 0.45 days 29.46 years
Uranus 0.72 days 84.01 years

Which major planet has the largest orbital eccentricity?

Mercury
The table lists the values for all planets and dwarf planets, and selected asteroids, comets, and moons. Mercury has the greatest orbital eccentricity of any planet in the Solar System (e = 0.2056).

### What planet has 48 hour days?

So, Venus has the longest day of any planet in our solar system. It completes one rotation every 243 Earth days. Its day lasts longer than its orbit.

Which planet has the most orbit?

According to Kepler’s laws, Mercury must have the shortest orbital period (88 Earth-days); thus, it has the highest orbital speed, averaging 48 kilometers per second. At the opposite extreme, Neptune has a period of 165 years and an average orbital speed of just 5 kilometers per second.

#### Which planet is the slowest to orbit the Sun?

A Year On Venus: In fact, Venus takes 243 Earth days to rotate once on its axis – the slowest rotation of any planet – and its rotation is retrograde to its orbital path.

What is the 8 largest planet?

Biggest Planets In Our Solar System

Rank ﻿Planet Diameter (Km)
5 Earth 12,756
6 Venus 12,104
7 Mars 6,779
8 Mercury 4,849

## Which planet has a longest day?

Venus
‘ It was already known that Venus has the longest day – the time the planet takes for a single rotation on its axis – of any planet in our solar system, though there were discrepancies among previous estimates. The study found that a single Venusian rotation takes 243.0226 Earth days.

What do planets orbit the Sun?

OBJECT. Distance traveled in one complete orbit of the Sun (one “year.”) Amount of time for one complete orbit of the Sun (one “year.”)

• Sun
• Mercury
• Venus
• Earth
• Mars. 23 Earth months. Almost 2 Earth years.
• Jupiter. 142 Earth months. Almost 12 Earth years.
• Saturn
• Uranus
• Neptune
• ### How do you find the orbital period?

Use Kepler’s Third Law to find its orbital period from its semi-major axis. The Law states that the square of the period is equal to the cube of the semi-major axis (P^2 = a^3). In order for the units to be correct, the semi-major axis should be in astronomical units, and the period should be in years.

What is the speed of rotation of the planets?

But due to it being a gas/ice giant, the poles of the planet rotate faster than the equator. Whereas the planet’s magnetic field has a rotational speed of 16.1 hours, the wide equatorial zone rotates with a period of about 18 hour. Meanwhile, the polar regions rotate the fastest, at a period of 12 hours.

#### What is the orbital speed of all planets?

Earth, our home planet of Earth speeds around the sun at a rate of 29.78 km/s. This means that we are traveling at 66,615 miles per hour. 4. Mars, with an orbital speed of 24.077 km/s, or 53,858 miles per hour, travels considerably faster than the prior planets.
