Question

if there is no releation between time and mass then why the time of Jupiter is 9 hours a day and Earth is 24hours a day​

Answer 1

Answer:

Because the Earth orbits the Sun elliptically as the Earth spins on an inclined axis, this period can be up to 7.9 seconds more than (or less than) 24 hours. ... The length of such a day is nearly constant (24 hours ± 30 seconds). This is the time as indicated by modern sundials.
