Belfast and Maston-- that it had deviated from its course from some unknown cause, and had not reached its destination; but that it had passed near enough to be retained by the lunar attraction; that its rectilinear movement had been changed to a circular one, and that following an elliptical orbit
round the star of night it had become its satellite.
For example, in thinking of the Solar System, you are likely to have vague images of pictures you have seen of the earth surrounded by clouds, Saturn and his rings, the sun during an eclipse, and so on; but none of these form part of your belief that the planets revolve round the sun in elliptical orbits
On the very same night, our only natural satellite enters its closest point to us in its elliptical orbit
QCH Astronomer Dr Beshir Marzouk said, Venus, like other planets, moves in its elliptical orbit

- it does not move around the Earth in a perfect circle.
Cassini is now on a looping elliptical orbit

Lockheed Martin is the prime contractor for SBIRS, which includes a combination of satellites in Geosynchronous Earth Orbit, hosted payloads in Highly Elliptical Orbit
, and ground hardware and software.
The observations, which the Trace Gas Orbiter (TGO) will carry out from its highly elliptical orbit
, will provide the science teams at ESA and Roscosmos a chance to calibrate their instruments.
The moon was at its brightest because it was the closest it has been to Earth, along its elliptical orbit
, since January 1948.
Supermoons happen because the elliptical orbit
of the moon occasionally brings it in line with the Sun and the Earth.
TEHRAN (FNA)- Earlier this year scientists presented evidence for Planet Nine, a Neptune-mass planet in an elliptical orbit
10 times farther from our Sun than Pluto.
