Which planet has the longest period of the revolution around the sun?
Neptune.
What is the longest period in the periodic table?
6th and 7th period are the longest period of the perodic table
What planet has the second shortest day?
Mercury has the 2nd longest "sidereal day" with a sidereal rotation period of 58.646 Earth days. The longest "sidereal day" day is Venus, with a sidereal rotation period of 243.018 Earth daysIf you use the "solar day" as your definition of "day", the order is reversed. Mercury then has the longest day and Venus has the second longest day.
Which planet is longest planet?
Jupiter is the largest with the largest diameter.
What planet travels the slowest around earth?
There are no planets in orbit around the Earth !. Orbiting the Sun - Pluto has the longest orbital period at 248 years - although it has now been declassified as a planet. This leaves Neptune - with an orbital period of just under 165 years.
What is the synodic period of the moon?
The synodic period of the moon is 29.5 days.
Which planet has the longest rotation period?
Pluto has the longest REVOLUTION period Venus has the longest ROTATION period
The planet with the longest period of revolution is?
Neptune.
What's the difference between a sidereal year and a synodic year?
A sidereal year is measured based on the planet's position in space relative to the background stars. A synodic year is measured based on the planet's position relative to the star it rotates around (i.e. the sun) Here's an image that is pretty helpful in visualizing.
Which planet has the longest period of the revolution around the sun?
Neptune.
Synodic period of the moon?
29.530588 days.
How long is a day and a year on the planet?
A planets day (solar day) is the time it takes to rotate once on its axis relative to the sun, the synodic period. A year on a planet is the time taken for the planet travel once around the sun.
Why stars seem to move faster than planets in the sky as viewed from earth?
It's because we are going round the Sun and so are all the planets. For that reason the time it takes for a planet to go round the ecliptic and arrive back at the same apparent position - called its synodic period - is longer than a year. Venus and Mars have the longest synodic period because their times to go round once are the closest to 365 days. They take 225 and 687 days to go round but the synodic periods are 584 and 780 days. On the other hand the far-out planets do not move much in a year. Neptune takes 165 years to go round so its synodic period is only a little over 365 days and is 367½ days.
What planet has the longest revolution?
If you mean revolution on it axis (spin/day length) rather than orbital period, then the answer is the planet Mercury, where time between sunrises is roughly 176 Earth days.
Missions to mars are launched about 26 months apart because that is the blank blank between earth and mars?
Yeah this is the Synodic Period... are you doing a crossword for a planet class right now... me too!
What planet requires one earth year to rotate on its axis?
There is no such planet known. The planet with the longest rotation period is Venus. That rotates in about 243 Earth days.
How long is Mars' orbital period?
686.980 earth days, sidereal period; 779.94 earth days, synodic period.
