Is there a china teapot revolving around the Sun in an elliptical orbit between Earth and Mars?
Hehe… ALL orbits are elliptical. “Circular” orbits, our moon almost has one, are just special cases where the axises are equal. In actuality, there are millions of tiny objects orbiting planets, stars, or other objects of sufficient size to attract them. While there may be man made objects with an orbit as you describe, I doubt that a china tea service is among them. Because of orbital mechanics, it would be virtually impossible to achieve that orbit in a device without rockets to adjust its position – If the object left the earth without the ability to alter its course in such a way that it began to orbit the sun, that orbit will, by definition, overlap earth’s orbit, resulting in a very high potential that it would be pulled into earth’s atmosphere on some future orbit and crash or burn up.
