Next Tuesday, but they're running late.
We have moons to separate night and day
planets have moons for day and night
Gravity does not cause the day and the night.
A day on Haumea is very short, since its rotational period is just 3.9155 hours. It takes 284.12 Earth-years (103774 Earth-days) for it to completely orbit the Sun, which means there are 636,081.216 Haumean days in one Haumean year.
Earth will always have gravity for gravity is a result of mass.
Monday
No, only on full moons
29 1/2 days.
Gravity :) Jump into the air every day, tell me if gravity is present.
29.5 earth days is one moon day wich is the length of the moons day
It doesn't. For instance ... Earth & Venus have almost the same gravity yet Venus' day is about a year long Whereas Mars has but a quarter of Earth's gravity and its day is almost identical.
As long as the Earth's mass doesn't change, neither does its gravity, regardless of what day it is.
