Trojan asteroid seen in Earth's orbit by Wise telescope. Read more about sharing. Astronomers have detected an asteroid not far from Earth, moving in the same orbit around the Sun. The 200-300m-wide rock sits in front of our planet at a gravitational sweet spot, and poses no danger.
Calories Burned. A half mile is a relatively short distance to run, so you shouldn't expect a big calorie burn. According to the website Cool Running, a 200-pound person will burn 79 calories running half a mile. A 175-pound person will use less energy, burning just 69 calories per half mile.
Compute your run training calorie burn and add that to your totals. For example, a 125-pound woman burns about 300 calories running for 30 minutes at a 6-mph pace. If you are running about 20 miles per week â approximately 3.5 hours -- youâll burn an extra 2,100 calories total, or about 300 extra calories daily. You can add that 300 calories to your daily calorie burn to figure how much you can eat daily. A rough estimate for a woman aged 31 to 50 years running 20 miles per week is between 2,100 and 2,500 calories.
