Which planets have shorter periods?
Which planets have shorter periods?
Mercury is the smallest planet and it also has the shortest orbital period. Earth and Venus are about the same size but Venus has a shorter orbital period as it is closer to the sun. Mars is smaller than Earth and Venus but has a longer orbital period as it is further from the sun. Jupiter is by far the largest planet.
Which planet has the shortest orbital period?
Mercury
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.
What is the orbital period for a short period come?
Short-period comets take less than 200 years, and long-period comets take over 200 years, with some taking 100,000 to 1 million years to orbit the Sun.
Do planets closer to the Sun have a shorter period?
Planets that orbit closer to the Sun than Earth have shorter years than Earth. Planets that orbit farther from the Sun than Earth have longer years than Earth. This happens for two main reasons. If a planet is close to the Sun, the distance it orbits around the Sun is fairly short.
What planet has the longest year?
Neptune
As such, a year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days).
Which is a Jovian planet?
Jupiter, Saturn, Uranus and Neptune collectively make up the group known as the jovian planets. Rather than having thin atmospheres around relatively large rocky bodies, the jovian planets have relatively small, dense cores surrounded by massive layers of gas.
What planet takes 7 years to orbit the Sun?
What are the orbital lengths and distances of objects in our solar system?
OBJECT | Distance from Sun (average) | Amount of time for one complete orbit of the Sun (one “year.”) |
---|---|---|
Sun | 0 miles | |
Mercury | 36,800,000 miles | 3 Earth months |
Venus | 67,200,000 miles | 7 Earth months |
Earth | 93,000,000 miles | 1 Earth year (365.25 days) |
What planet is made of 2/3 water?
The Earth is the only planet known where life exists. Almost 1.5 million species of animals and plants have been discovered so far, and many more have yet to be found. While other planets may have small amounts of ice or steam, the Earth is 2/3 water. Earth has perfect conditions for a breathable atmosphere.
What is Mars orbital period?
687 days
Mars/Orbital period
What is Earth’s orbital period?

Earth/Orbital period
How is 1 hour in space equal to 7 years on Earth?
Answer: The time-dilation effect of Einstein’s relativity has nothing to do with space. The faster you’re moving, the slower time goes for you. So if you were on some planet moving extremely fast through space, like in the movie Interstellar, then you could miss 7 years on Earth every hour.
What are the planets in the Sky Tonight?

Which is the hardest planet to see in the night sky?
Of this list, Mercury can be the hardest one to spot… it is the closest planet to the Sun and is never seen too far from the Sun, so its low altitude and the glare of the rising or setting sun can make it hard to pick out. Are Planets Visible At the Same Time Each Year?
Is the synodic period of the Sun infinitely long?
If there were to be another planet that orbited the Sun at exactly the same distance as the Earth, it would orbit the Sun at exactly the same rate as the Earth and never overtake it – its synodic period would be infinitely long. The equation for this is as follows:
Is the planet Mercury visible in the night sky?
Mercury is close to the Sun and can only be seen shortly after sunset. Try finding a good, unobstructed view of the horizon. Fairly close to the Sun. Visible around sunset only. Venus is just 11 degrees from the Sun in the sky, so it is difficult to see.
