The most distant takes 20 days to orbit the star.

It takes over a decade to orbit the star.

However, until the 2010 observations and recalculations, this planet had been thought to take about 2.8 days to orbit the star.

It orbits the star in a very tight orbit, completing one revolution around the star in every three and half days or so.

As of 2009, an extrasolar planet has been confirmed to orbit the star.

The planet orbits in an area known as the “snow line,” where rocky bodies tend to give way to icier bodies.

Planet orbits are in general elliptical, a perfect circle being the exceptional case rather than the rule.

This planet orbits in a very eccentric path around the star with a period of about four years.

Light green rows indicate that the planet orbits one of the stars in a binary star system.

The planet orbits the star in a rather eccentric orbit.

This might also include transformation of the surface conditions, changes in the planetary orbit, and structures in orbit intended to modify the energy balance.

The required sail orientation changes slowly (often less than 1 degree per day) in interplanetary space, but much more rapidly in a planetary orbit.

In celestial mechanics, he found improved methods to deduce a planetary orbit from observations, and analysed the mathematics of perturbations in planetary motions.

Let be the conventional polar angle describing a planetary orbit.

A growing dragon flew into planetary orbit and fell.

It only takes eightand-a-half minutes to reach orbit, then you're floating in space, looking down at the planet.

But the rocket’s second stage engine switched off too early, and the satellite did not reach orbit.

Neither was a ground-launched rocket with the ability to reach orbit, as a rocket must do to launch heavy payloads, however.

Though the craft will not reach orbit, its passengers will experience weightlessness and spectacular views of the planet.

Boosters will fall away as the capsules reach orbit.
