Estimate the mass of the Sun from the orbital period of the Earth (it’s presumed you know what this is !) and the Earth’s orbital radius of 93 million miles. If the Sun’s radius is 109 times that of the Earth, what is the Sun’s mean density? What is the acceleration due to gravity on the Sun’s surface? Is it sensible to go and measure this at night?

The table below shows how much of the mass of the Sun and the
Earth are made up of each element (by mass). Note that, for this
problem, the amounts have been randomized somewhat from their real
values. For your answers to this problem, use the values given in
the table below. Note that because of rounding, uncertainties in
the known values, the applied randomization, and small differences
between the solar nebula composition and the composition of the
Sun, it...

What's ratio of the orbital period for a satellite in
a geosynchronous orbit around the Earth to that of a satellite in
an orbit slightly above the surface of the Earth? The Earth has a
radius of 6371km, and a satellite in a circular geosynchronous
orbit has a radius of 42000km from the center of the earth. The
mass of the Earth is 5.792*10^24kg, and Newton's gravitation
constant is G=6.674*10^-11N*m^2/kg^2

Estimate the initial rotation period of the Earth if the Moon
had been torn from it, as suggested by the fission theory. Compare
your answer to the estimated rate of spin of the early Earth (5
hours or so). Is the fission theory a viable theory?

Earth’s orbit is 150 Gm. The radius of Jupiter is 69.9 Mm and the
average radius of Jupiter’s orbit is 778 Gm
