Carefully weigh the known risks of bisphosphonate drugs against their potential benefits. En espaÃ±ol | Q. I'm a 62-year-old woman with osteoporosis (as determined by a -2.87 on my bone density scan). I've been taking Fosamax along with calcium and vitamin D supplements for the past five to six years.

Earth's orbit. Earth's orbit is the path through which the Earth travels around the Sun. The average distance between the Earth and the Sun is 149.60 million kilometers (92.96 million miles), and a complete orbit occurs every 365.256 days (1 sidereal year), during which time Earth travels 940 million kilometers (584 million miles). Earth's orbit has an eccentricity of 0.0167.
One orbit of the Earth takes one year. Meanwhile, our entire solar system â our sun with its family of planets, moon, asteroid and comets â orbits the center of the Milky Way galaxy. Our sun and solar system move at about about 500,000 miles an hour (800,000 km/hr) in this huge orbit.
