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.
A year is defined as the amount of time it takes for a planet to make an orbit around the sun. On Earth, this amount of time is 365 days and that's what we call a year. On Neptune, which is 30 astronomical units away or 30 times the distance, a year takes 165 Earth years so it takes 165 years for Neptune to complete its orbit and that is how long a Neptune year is.
