parabolic orbit

All you need do is to go into a parabolic orbit and let yourself fall in like a comet going round the Sun.

"Have none to waste in a parabolic orbit," his friend replied.

Special cases with fewer degrees of freedom are the circular and parabolic orbit.

Although the eccentricity is 1 this is not a parabolic orbit.

He authored approximately 180 research papers and modified the method of determining parabolic orbits.

Insertion parabolic orbit Terraluna to commence at 2010 hours.

Parabolic orbits diagrammed against the concentric circular paths of the planets.

For a hyperbolic orbit, it is equal to the excess energy compared to that of a parabolic orbit.

The parabolic orbit is the degenerate intermediate case between those two types of ideal orbit.

"Yuen apparently believes that with such an eccentric, almost parabolic orbit, this Pluto body may exit the star system again, or fall into the sun."

They swung about the star in a parabolic orbit, for, at their velocity, the sun could not hold them in a planetary orbit.

This should be distinguished from the parabolic orbit in the sense of astrodynamics, where the velocity is the escape velocity.

At the lowest altitude in the parabolic orbit, though, the Sun's huge horizon rimmed white-hot in all directions.

Parabolic orbits do not occur in nature; simple orbits most commonly resemble hyperbolas or ellipses.

You can't get the observed nearly parabolic orbits out of an Oort cloud; so said R. A. Lyttleton.

After others had shown that Uranus was not on a parabolic orbit but rather in a roughly circular orbit, he calculated the orbit in 1783.

The ships rode side by side, drifting in the comet's slipstream as it cruised on its long parabolic orbit around a forgotten and uninteresting solar system.

Note: The fact that a parabolic orbit has zero energy arises from the assumption that the gravitational potential energy goes to zero as the bodies get infinitely far apart.

For an elliptical orbit the specific orbital energy is the negative of the additional energy required to accelerate a mass of one kilogram to escape velocity (parabolic orbit).

Moreover, Comet Wilson, with its parabolic orbit, may be a "new" comet, making its first entry into the inner solar system, as opposed to a "rediscovered" one like Halley's.

In this case the specific orbital energy is also referred to as characteristic energy (or ) and is equal to the excess specific energy compared to that for a parabolic orbit.

In 1664-1665 he made observations of comets, and argued in favor of their following elliptical or parabolic orbits (in this he was opposed by his rival Johannes Hevelius).

The orbit is a parabolic orbit, a hyperbolic orbit, or part of an elliptic orbit which ends at the planet's surface at the point of launch or another point.

All the estimates that I've seen agree that the probability of Jupiter deflecting incoming comets from vast distances on parabolic orbits to an elliptical one is about one in a hundred thousand.

But to break the vast parabolic orbit a body would naturally attain in falling from Earth toward the Sun would require every pound of fuel the Prometheus could carry and break free of Luna.
