Question

Define Orbital plane and Leap year

Answer 1

Hey mate here is your answer

Orbital Plane:- All of the planets, comets, and asteroids in the solar system are in orbit around the Sun. All of those orbits line up with each other making a kind of flat disk called the orbital plane. The planets all orbit on or near one plane in space like the picture above.


Leap Year:- Occurs every 4 years and adds one extra day to the month of February. This rare occurrence increases the standard 365-day year to 366 days. The leap year is necessary to keep the calendar year synchronized with the astronomical year.

Hope this answer will help you!!

Answer 2

The orbital plane of a revolving body is the geometric plane on which its orbit lies. A common example would be the centers of a massive body, of an orbiting body, and of the orbiting object at another time.

A leap year (also known as an intercalary year or bissextile year) is a calendar year containing one additional day (or, in the case of lunisolar calendars, a month) added to keep the calendar year synchronized with the astronomical or seasonal year.[1] Because seasons and astronomical events do not repeat in a whole number of days, calendars that have the same number of days in each year drift over time with respect to the event that the year is supposed to track. By inserting (also called intercalating) an additional day or month into the year, the drift can be corrected. A year that is not a leap year is called a common year.
