Which terrestrial planet has the longest year?
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.
What is the term for longest night?
The longest night of the year is called the Winter Solstice.However, it is worth noting that at latitudes of higher than 66.5 degrees north or south that there may be more than one day of 24-hour darkness in a year, meaning that the night of the Winter Solstice may not be the longest night of the year, just one of the longest nights of the year. Conversely, on the equator, all days and nights are exactly 12 hours each, so technically, there is no longest night on the equator.
What is the definition of the light year?
