5 After browning the roast at a 500Â°F temperature in the oven for 15 minutes, reduce the oven temperature to 325Â°F. To figure out the total cooking time, allow about 12-14 minutes per pound for rare and 15-17 minutes per pound for medium rare.
The length of a day on Neptune, also known as its period of rotation, is about 16.1 Earth hours, or 0.67 Earth days. The length of a year on Neptune, also known as its per â¦ iod of revolution, is 164.8 Earth years, or 60,190 Earth days.
Neptune has 13 moons, many fewer than any of the other Jovian planets. Neptune has 17.2 Earth masses, so it is more massive than Uranus. Note, however, that it is smaller in size than Uranus, having a radius of 24,700 km. Thus, it must have a higher density: 1.63 gm/cm 3.Neptune has a rotation period of 16 hours.eptune has 17.2 Earth masses, so it is more massive than Uranus.
