1 solar day is equal to how many hours
Day In common usage, it is either an interval equal to 24 hours[4] or daytime, the consecutive period of time during which the Sun is above the horizon. The word day may also refer to a day of the week or to a calendar date, as in answer to the question, "On which day?" The life patterns (circadian rhythms) of humans and many other species are related to Earth's solar day and the day-night cycle.
Solar eclipse of August 21, 2017 The longest ground duration of totality was 2 minutes 41.6 seconds at about 37°35′0″N 89°7′0″W﻿ / ﻿37.58333°N 89.11667°W﻿ / 37.58333; -89.11667 in Giant City State Park, just south of Carbondale, Illinois, and the greatest extent (width) was at 36°58′0″N 87°40′18″W﻿ / ﻿36.96667°N 87.67167°W﻿ / 36.96667; -87.67167 near the village of Cerulean, Kentucky, located in between Hopkinsville and Princeton.[10] This was the first total solar eclipse visible from the Southeastern United States since the solar eclipse of March 7, 1970. Two NASA WB-57F flew above the clouds, prolonging the observation time spent in the umbra.[11] A partial solar eclipse was seen from the much broader path of the Moon's penumbra, including all of North America, particularly areas just south of the totality pass, where the eclipse lasted about 3–5 hours, northern South America, Western Europe, and some of Africa and north-east Asia.
