The solar year, the time it takes for the Earth to complete one solar orbit, is 365 days, 5 hours, 48 minutes and 45½ seconds. In order to make the average calendar year close to the length of an actual year, we add an extra day to the standard 365-day calendar 97 times every 400 years. That makes the average calendar year 365 days, 5 hours, 49 minutes and 12 seconds. That is 26½ seconds longer than an actual year, resulting in an extra day every 3260 years.
The sun is the mass centre of the solar system.
There is no actual pollution from solar energy - apart from the pollution caused in the manufacture of the solar panels.
Probably whenever there is a solar eclipse.
It's the average length of the "apparent solar day" throughout the year, 24 hours exactly for planet Earth.

A solar calendar is a type of calendar that is based on the position of the Earth in relation to the sun. This means that the calendar is organized around the length of the solar year, which is the time it takes for the Earth to complete one orbit around the sun. Solar calendars are used to keep track of the seasons and to organize events and appointments throughout the year. Some examples of solar calendars include the Gregorian Calendar, the Julian Calendar, and the Hindu Calendar. The solar calendar is the most widely used calendar system in the world and is the standard for civil and commercial purposes.
The time based on the average length of a day throughout a year is called Mean Solar Time. This time standard is used in civil timekeeping to account for variations in the length of a solar day due to the Earth's elliptical orbit and axial tilt.
No, Charon is not the biggest moon in the solar system. The actual biggest moon in the solar system is Ganymede, which is 5,268 km at the equator
A solar cell will vary in length, width, and weight. Solar cells were first used in 1873 by an inventor named Charles Fritts.
are affected by cloud coverage and day length"
The real solar system consists of the sun, planets, moons, asteroids, and comets in actual space. A model of the solar system is a representation of the real solar system, typically smaller in scale and used for educational purposes. The real solar system is dynamic and follows the laws of physics, while a model offers a simplified version for easier understanding.
