The melody commonly associated with the rhyme was first recorded by the composer and nursery rhyme collector James William Elliott in his National Nursery Rhymes and Nursery Songs (1870). The word "sport" in the rhyme is sometimes replaced with "fun", "a sight", or "craft". [4]
Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...

Moons have come to exist around most planets and many other Solar System bodies. These natural satellites originated by one of three possible mechanisms: Co-formation from a circumplanetary disc (only in the cases of the giant planets); Formation from impact debris (given a large enough impact at a shallow angle); and; Capture of a passing object.
A nursery rhyme is a traditional poem or song that's told or sung to young children. The term dates back to the late-18th and early-19th centuries in Britain where most of the earliest nursery rhymes that are known today were recorded in English but eventually spread to other countries. [6]
The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object. In astronomy, it usually applies to planets or asteroids orbiting the Sun, moons orbiting planets, exoplanets orbiting other stars, or binary stars.
The Sun is moved by the gravitational pull of the planets. The center of the Sun moves around the Solar System barycenter, within a range from 0.1 to 2.2 solar radii. The Sun's motion around the barycenter approximately repeats every 179 years, rotated by about 30° due primarily to the synodic period of Jupiter and Saturn. [152]
