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.

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).

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

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.

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.

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

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.

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

Since is just an equilibrium point with no gravitational pull, a halo orbit is not an orbit in the usual sense the spacecraft is actually in orbit around the Sun, and the halo orbit can be thought of as controlled drifting to remain in the vicinity of the point.

Time in orbit Ground controllers did not know if a stable orbit had been achieved until 25 minutes after launch.

Apart from those in sun synchronous orbit, few satellites are launched into retrograde orbit because the quantity of fuel required to launch them is much greater than for a prograde orbit.

General Relativity Orbit Tracer

They are situated in the upper, outer portion of each orbit, in the lacrimal fossa of the orbit formed by the frontal bone.

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.

Until 21 March 2001 it was the largest satellite in orbit, succeeded by the International Space Station after Mir's orbit decayed.

Most of them should be in orbit around something.

On 19 June, Salyut 6 was in a orbit.

Many moons orbit around Saturn.

Many satellites orbit the earth.

Sirius has an elliptical orbit.

As it arrived, the spacecraft did not go into orbit around the asteroid, but remained in a station keeping heliocentric orbit close by.

Bob Bigelow currently has a test article in the orbit.

The first stage of the IUS placed TDRS 3 in a transfer orbit, and the second stage placed it in a geosynchronous orbit on 30 September.

In turn, angular momentum is added to the Moon's orbit, accelerating it, which lifts the Moon into a higher orbit with a longer period.

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.

They tell Gagarin that Vostok 1 is in a stable orbit.

The vulcanoids are a hypothetical population of asteroids that may orbit the Sun in a dynamically stable zone inside the orbit of the planet Mercury.

New Horizons took only nine hours to reach the Moon's orbit, passing lunar orbit before midnight EST that day.

The escape velocity at a given height is formula_9 times the speed in a circular orbit at the same height, (compare this with the velocity equation in circular orbit).

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.

It has moved into its own orbit.

Civilian low Earth orbit communication satellite system.

It was successfully deployed on orbit 64.

He was in orbit from 6 June 1976 to 24 August 1976.

Orbit Ceres follows an orbit between Mars and Jupiter, within the asteroid belt, with a period of 4.6 Earth years.

Derivation of geostationary altitude In any circular orbit, the centripetal force required to maintain the orbit (Fc) is provided by the gravitational force on the satellite (Fg).

Discovery landed on 18 March 1989, after orbit 80, one orbit earlier than planned, in order to avoid possible excessive wind buildup expected at the landing site.

Some satellites, notably space stations, have been launched in parts and assembled in orbit.

It has a fairly substantial number of asteroids between the orbit of the Earth out through to the orbit of Jupiter.

It is seen from, in this case, from outside the orbit of Saturn.

Space access Transportation to orbit is often the limiting factor in space endeavours.
