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.
The 12 to 18 hour rotation periods found for the atmospheric features differ from the above value because of winds. (see the related link for additional information) It takes Neptune 16 hours and 6 minutes to rotate once on its axis.  This means that one day on Neptune is the same as about 16 hours on  Earth.
