Tell us what a 'day' on the sun might be, and we'll be able to answer that.
Obviously, it can't be the cycle of light and dark, because it never gets dark anywhere on the sun.
If you're asking about the sun's rotation on its axis ... since the sun isn't even solid,
it doesn't have to rotate all in one piece, so it doesn't. Different latitudes rotate with
different periods. The range of rotation periods between the sun's equator and poles
is about 32 to 36 earth days.
Full sun is best but,,, at least 8 to 10 hours minimum.
Mint plants grow in full sun or in partial shading. Six or more hours of full sun exposure is best.
This phenomenon is known as midnight sun, typically occurring in regions near the North or South Pole during their respective summer months, when the sun remains visible for a full 24 hours.
it takes Neptune 164.79 years to revolve around the sun. There are two rotations for a planet, that of its own rotation, and that of its rotation round the sun. Equivalent to our Day and Year.
One full rotation on its axis: 23 hours 56 minutes (sidereal), 24 hours (tropical). The difference between the two is whether you measure it relative to the distant stars (sidereal) or the Sun (tropical). One full rotation around the sun: 365.25 days
Regularly, Full Sun is appx. 6 to 8 hours of bright sun.
Full sun is best but,,, at least 8 to 10 hours minimum.
Full sun to partial shade.
Iris need full sun, at least six hours a day.
Peonies require full sun. They should have at leasst 4-6 hours of sun a day.
This depends on the type of plant and its specific needs. Plants that require full sun will need minimally six hours of sun per day. Plants that require partial sun will need 4-6 hours of sun per day. Plants that require partial shade will need 2-4 hours of sun per day, and plants that require full shade will need no direct sunlight or no more than 2 hours per day.
the sun is at its precipice at 12 noon everyday. therefore it would have to be a full 24 hours before the sun hit the precipice again.
24 hours
The Earth rotates about its axis, causing the sun to rise and set. A full rotation happens every 23.934 hours. (Which is close to 24 hours, which is why a full day-night cycle is about 24 hours long.)
365.256363004 days = 8,766.15271 hours
about 41 hours the full answer is 41.66
12 hours
