Distance to MarsDate: 07/25/97 at 18:13:15 From: Elsa Gonzalez Subject: Distance to Mars What is the distance from Earth to Mars? Date: 07/28/97 at 13:22:12 From: Doctor Rob Subject: Re: Distance to Mars That varies depending on the positions of Mars and the Earth in their orbits. The closest they come is R - r, and the farthest they get is R + r, where R is the radius of the orbit of Mars, and r is the radius of the orbit of the Earth. For a first approximation, r = 93,000,000 miles and R = 141,000,000. Actually this is only approximate, because the orbits are both elliptical. Mars ranges from 126,000,000 to 156,000,000 miles from the Sun, while Earth's orbit is much closer to being circular. As a result, the closest they could come would be 33,000,000 miles, and the farthest 249,000,000 miles. -Doctor Rob, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
