Question: What Planet Has The Longest Synodic Period?

Why is the synodic period longer?

However, because the Earth is constantly moving along its orbit about the Sun, the Moon must travel slightly more than 360° to get from one new moon to the next.

Thus, the synodic month, or lunar month, is longer than the sidereal month.

A sidereal month lasts 27.322 days, while a synodic month lasts 29.531 days..

Is there life on Mars?

To date, no proof has been found of past or present life on Mars. Cumulative evidence shows that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms.

What is the synodic period of a planet?

The synodic period of a planet is the time required for the Earth to overtake it as both go around the Sun—or, in the case of fast-moving Mercury or Venus, for the planet in question to overtake the Earth.

What is the synodic period of Venus?

584 daysIt just so happens that the synodic period of Venus (584 days) relates to the orbital period of the earth (365 days) in a relatively simple ratio of 5:8.

How long is a year on Venus?

225 daysVenus/Orbital period

Why does Mars have the longest synodic period?

Mars’ sidereal period would equal its synodic period because Earth would be stationary. Because both planets move, Earth needs slightly more than two years to align itself with Mars after each opposition. … Mars has the longest synodic period because it moves such a great distance during each Earth year.

What is Mars orbital period?

687 daysMars/Orbital period

Why is Mars red?

Mars is red now, but it may have looked like charcoal in the past. … The simple explanation for the Red Planet’s color is that its regolith, or surface material, contains lots of iron oxide — the same compound that gives blood and rust their hue.

How long is synodic period?

29.5 daysThe period of the lunar phases (the synodic month), e.g. the full moon to full moon period, is longer at ~29.5 days. At New Moon, the Moon is aligned with the Sun. During the lunar month the Earth orbits (revolves) ~30° around the Sun and the Moon orbits (revolves) ~390° to align with the Sun again.

What is the synodic period of Mars?

780 daysIn the case of Mars the sidereal period, is 687 days, the synodic period 780 days.

Is Venus called the Evening Star?

How many miles is it to the moon?

384,400 kmMoon/Distance to Earth

Which planet has the longest sidereal period?

MarsOf all the major planets, Mars has the longest synodic period, namely 780 days, so that it comes to opposition and is easy to observe at intervals of a little more than two years.

What is Earth’s orbital period?

365 daysEarth/Orbital period

What is an inferior planet?

The inferior planets are those which orbit closer to the Sun than the Earth, namely Mercury and Venus.

What year will Mars be closest to Earth?

Today at 10:18 a.m. EDT (1418 GMT), Mars swoops within 38,568,816 miles (62,070,493 kilometers) of Earth, making a smooth close approach. This will be the closest the Red Planet will come to Earth for the next15 years, or until September, 2035, according to Earthsky.org.
