Pluto has the longest year, if it was still a planet that is, equal to 248.76 Earth years. Since Pluto is no longer considered a planet, the planet with the longest year is Neptune, at 164.8 Earth years per revolution around the Sun.
Mercury, at about 88 Earth days.
Actually, June 21 is typically the longest day of the year in the Northern Hemisphere, not the shortest. This day marks the summer solstice, when the North Pole is tilted closest to the sun, resulting in the longest period of daylight. Conversely, the shortest day of the year occurs around December 21, during the winter solstice, when the North Pole is tilted farthest from the sun.
On December 21, the Earth is positioned at the December solstice. This is when the Northern Hemisphere experiences the winter solstice, marking the shortest day and longest night of the year, while the Southern Hemisphere experiences the summer solstice, with the longest day and shortest night of the year.
All these are given in Earth days, and have been rounded to the nearest day The second figure given is their semi-major axis, in kilometres # Mercury -------- 88 .......... 57,909,100 # Venus --------- 225 ........ 108,208,930 # Earth ---------- 365 ........ 149,597,888 # Mars ----------- 687 ........ 227,939,100 # Jupiter ------ 4.332 ........ 778,547,200 # Saturn ---- 10,832 ...... 1,433,449,370 # Uranus ---- 30,799 ...... 2,876,679,082 # Neptune -- 60,190 ....... 4,503,443,661
The order of the planets by longest year is the normal order (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune). The farther away a planet's orbit is from the Sun, the longer the year.
(The year is proportional to the distance to the power 1.5) In our solar system, Mercury has the shortest year. Neptune has the longest.
the longest
Neptune has the longest year( Pluto would be but it isn't a planet) Mercury has the shortest year(1 year=88 earth days)
Yes. Longest day of the year in one hemisphere, and shortest day of the year in the other hemisphere. So our summer solstice on June 21 is the longest day in Europe or America, but the shortest day for the Australians.
No, the shortest.
The're the longest and shortest days of the year!
