Astrophysicists believe that our sun started out as a large cloud of hydrogen gas. Gravitational attraction between the gas molecules caused it to collapse. We can approximate both the initial cloud of gas and the sun to be spheres of uniform density. The mass of the initial cloud of gas and the sun are the same. The radius of the sun is much smaller than the radius of the initial cloud of gas. The sun now spins once every 24.5 days. The rotational kinetic energy of the sun is .

Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?
We know that we can use Kepler's Laws to determine the orbits objects around one another. We also have learned that most stars orbit at least one other star (two stars orbiting each other is called a binary system). With this in mind, let's figure out the total mass of both stars of a binary system. Observing the spectra of the two stars orbiting one another, we determine the orbital period of this set of example stars around the system's center of mass to be 0.25 years (1/4 of a year) and the separation of the two stars to be 0.75 AU (3/4 of an AU). With this information, what is the sum of the mass of these two example stars orbiting each other?
The mass of the sun is 2.0 x 1030 kg, and the mass of a hydrogen atom is 1.67 x 10-27 kg. If we assume that the sun is mostly composed of hydrogen, how many atoms are there in the sun?

he Sun’s mass is 2.0×1030kg, its radius is 7.0×105km, and it has a rotational period of approximately 28 days. If the Sun should collapse into a white dwarf of radius 3.5×103km,, what would its period be if no mass were ejected and a sphere of uniform density can model the Sun both before and after
Suppose you observe a binary system containing a main-sequence star and a brown dwarf. The orbital period of the system is 1 year, and the average separation of the system is 1 AU . You then measure the Doppler shifts of the spectral lines from the main-sequence star and the brown dwarf, finding that the orbital speed of the brown dwarf in the system is 23 times greater than that of the main-sequence star. How massive is the brown dwarf in kg?
After the Sun exhausts its nuclear fuel, its ultimate fate may be to collapse to a white dwarf state. In this state, it would have approximately the same mass as it has now, but its radius would be equal to the radius of the Earth.Calculate the average density of the white dwarf.Calculate the surface free-fall acceleration.Calculate the gravitational potential energy associated with a 6.69-kg object at the surface of the white dwarf.
In 1999, scientists discovered a new class of black holes with masses 100 to 10,000 times the mass of our sun that occupy less space than our moon. Suppose that one of these black holes has a mass of 1x10^3 suns and a radius equal to one-half the radius of our moon. What is the density of the black hole in g/cm^3? The radius of our sun is 7.0x10^5 km, and it has an average density of 1.4x10^3 kg/m^3. The diameter of the moon is 2.16x10^3 miles.

A massive black hole is believed to exist at the center of our galaxy (and most other spiral galaxies). Since the 1990s, astronomers have been tracking the motions of several dozen stars in rapid motion around the center. Their motions give a clue to the size of this black hole. a.
