We learn about its orbit, the period of its orbit and so on.

the average speed as it completes an orbit, or the speed at a particular point in its orbit.

It has moved into its own orbit.

A Sun synchronous orbit (sometimes called a heliosynchronous orbit) is a geocentric orbit which combines altitude and inclination in such a way that an object on that orbit will appear to orbit in the same position, from the perspective of the Sun, during its orbit around the Earth.

The shuttle's orbit in this mission was its highest orbit up to that date, in order for HST to be released near its operational altitude well outside the atmosphere.

A short period of thrust in the direction of motion accelerates or decelerates the spacecraft into an elliptical orbit around the Sun which is tangential to its previous orbit and also to the orbit of its destination.

Another hypothesis suggests that its orbit may be evidence for a large planet beyond the orbit of Neptune.

The satellite was deployed on the 7th orbit, and ignited its Inertial Upper Stage (IUS) booster at the ascending node of the 8th orbit, successfully placing it in a geosynchronous transfer orbit.

Its orbit around the planet was highly eccentric ( e 0.9986).

Pluto fails to meet the third condition, because its mass is only 0.07 times that of the mass of the other objects in its orbit (Earth's mass, by contrast, is 1.7 million times the remaining mass in its own orbit).

In effect, it orbits its star in isolation, as opposed to sharing its orbit with a multitude of similar sized objects.

This notion has been heavily criticized because Pluto never comes near Neptune in its orbit.

Orbit and classification Makemake is currently from the Sun, almost as far from the Sun as it ever reaches on its orbit.

A satellite's useful life is over once it has exhausted its ability to adjust its orbit.

The spacecraft falls freely along this elliptical orbit until it reaches its destination, where another short period of thrust accelerates or decelerates it to match the orbit of its destination.

In modern times, an asteroid receives a sequential number only after its orbit is precisely known.

The mission marked the first direct ascent trajectory for the Space Shuttle Challenger reached its 288 nautical mile (533 km) high orbit using its Orbiter Maneuvering System (OMS) engines only once, to circularize its orbit.

These previous positions expanded its known orbital arc and allowed a more precise calculation of its orbit.

This distance is not the same as its apastron, because no planet's orbit has its star at its exact centre.

In orbit, any additional impulse, even very tiny, will result in a change in the orbit path.

Approximately 500 operational satellites are in low Earth orbit, 50 are in medium Earth orbit (at 20,000 km), the rest are in geostationary orbit (at 36,000 km).

A planet that has cleared its neighborhood has accumulated enough mass to gather up or sweep away all the planetesimals in its orbit.

As it moves around its orbit, Venus displays phases like those of the Moon in a telescopic view.

And the things that relate to Ford enter its orbit and swirl around it.

Only after it was rediscovered could its orbit be established and a number assigned.

Relationship to Earth Orbit The Moon makes a complete orbit around Earth with respect to the fixed stars about once every 27.3 days (its sidereal period).

Each planet has two in the course of its orbit when one hemisphere has its summer solstice, when its day is longest, the other has its winter solstice, when its day is shortest.

Transits of Venus occur when the planet's inferior conjunction coincides with its presence in the plane of Earth's orbit.

Stars will orbit the black hole in the very same way that planets orbit the sun.

Regardless of which convention is used, Uranus has a retrograde rotation relative to its orbit.

Bode concluded that its near circular orbit was more like a planet than a comet.

It then executed three Orbital Manoeuvering System (OMS) burns, the last on its fourth orbit.

Hohmann transfer orbit An orbit that moves a spacecraft from one approximately circular orbit, usually the orbit of a planet, to another, using two engine impulses.

At least one extrasolar planet, WASP 17b, has been found to orbit in the opposite direction to its star's rotation.

Geostationary orbit (GEO) A geosynchronous orbit with an inclination of zero.

Launched in 1958, Vanguard 1, the 4th manmade satellite put in Geocentric orbit, was still in orbit as of August 2009.

Its distance from the Sun at perihelion was 0.23 AU, well inside the orbit of Mercury.

Thus, Oort reasoned, a comet could not have formed while in its current orbit and must have been held in an outer reservoir for almost all of its existence.

If Mars had an Earth like orbit, its seasons would be similar to Earth's because its axial tilt is similar to Earth's.

First, during its first five orbits of the planet (one Earth week), MRO used its thrusters to drop the periapsis of its orbit into aerobraking altitude.

The period of one revolution of a planet's orbit is known as its sidereal period or year .

On an elliptical orbit, a body's distance from the Sun varies over the course of its year.

Elliptic orbit An orbit with an eccentricity greater than 0 and less than 1 whose orbit traces the path of an ellipse.

You'd pay 10,000 dollars for that in orbit.

Because Uranus orbits the Sun almost on its side, and its moons orbit in the planet's equatorial plane, they (including Titania) are subject to an extreme seasonal cycle.
