Next Tuesday, but they're running late.
We have moons to separate night and day
planets have moons for day and 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.
how many grams of saturated fat are you supposed to have in a day for it to be healthy?
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.
No, gravity does not change throughout the day. It remains constant, exerting a consistent force on objects.
The glare of sunlight dominates the sky.
