List of orbits Various earth orbits to scale; cyan represents low earth orbit, yellow represents medium earth orbit, the black dashed line represents geosynchronous orbit, the green dash-dot line the orbit of Global Positioning System GPS satellites, and the red dotted line the orbit of the International Write about artificial satellites names Station ISS.

The first satellite, Sputnik 1was put into orbit around Earth and was therefore in geocentric orbit. By far this is the most common type of orbit with approximately 1, [19] artificial satellites orbiting the Earth. Geocentric orbits may be further classified by their altitude, inclination and eccentricity.

Low Earth orbit is any orbit below 2, km. Centric classifications[ edit ] Geocentric orbit: An orbit around the planet Earth, such as the Moon or artificial satellites. Currently there are approximately 1, [19] artificial satellites orbiting the Earth.

Space machines do not orbit the Earth – The Wild Heretic

An orbit around the Sun. In our Solar Systemall planets, cometsand asteroids are in such orbits, as are many artificial satellites and pieces of space debris. Moons by contrast are not in a heliocentric orbit but rather orbit their parent planet. An orbit around the planet Marssuch as by moons or artificial satellites.

The general structure of a satellite is that it is connected to the earth stations that are present on the ground and connected through terrestrial links.

Also known as an intermediate circular orbit. The period of the orbit equals one sidereal daycoinciding with the rotation period of the Earth.

High Earth orbit HEO: Orbital Altitudes of several significant satellites of earth. Inclination classifications[ edit ] Inclined orbit: An orbit whose inclination in reference to the equatorial plane is not zero degrees.

An orbit that passes above or nearly above both poles of the planet on each revolution. Therefore, it has an inclination of or very close to 90 degrees. Polar sun synchronous orbit: A nearly polar orbit that passes the equator at the same local time on every pass.

Useful for image taking satellites because shadows will be nearly the same on every pass. Eccentricity classifications[ edit ] Circular orbit: An orbit that has an eccentricity of 0 and whose path traces a circle.

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

Satellites, Non-Governmental High Resolution That will tell us where we need to put research effort, and where that will lead to progress towards our Super Intelligence. The seven capabilities that I have selected below start out as concrete, but get fuzzier and fuzzier and more speculative as we proceed.

The perihelion of the transfer orbit is at the same distance from the Sun as the radius of one planet's orbit, and the aphelion is at the other. The two rocket burns change the spacecraft's path from one circular orbit to the transfer orbit, and later to the other circular orbit.

This maneuver was named after Walter Hohmann. An orbit with an eccentricity greater than 0 and less than 1 whose orbit traces the path of an ellipse.

An elliptic orbit where the perigee is at the altitude of a Low Earth orbit LEO and the apogee at the altitude of a geosynchronous orbit. An elliptic orbit where the perigee is at the altitude of a Low Earth orbit LEO and the apogee at the altitude of a geostationary orbit. A highly elliptic orbit with inclination of Click on the names below to jump to their section of the list.

THE TOP 10 1. The Students Marjory Stoneman Douglas and other schools 2. Bill and Melinda Gates Cofounders, Gates Foundation 3. The #. Satellites. This is a list of all Indian (wholly or partially owned, wholly or partially designed and/or manufactured) satellites, both operated by the Indian government (ISRO, Indian defence forces, other government agencies) or private (educational and research) entities.

Introduction Though perhaps best known throughout the world for his science fiction, Isaac Asimov was also regarded as one of the great explainers of science.

The essential tech news of the moment. Technology's news site of record. Not for dummies. Epilogue (part 1) - my views Introduction, or: what is it about the Voynich MS, really Nowadays, more people are aware of the existence of this mysterious Voynich MS than ever before.

This is clearly due to the advance of the internet into everyday life, and the occasionally increased media attention. From down here on the ground, space looks like a pristine void. But Earth's orbit is actually crowded with a ton of stuff, from human-made satellites to many smaller pieces of debris whirling around at dangerously high speeds, as the film Gravity so memorably dramatized.

In fact, there are an estimated , or so smaller orbital debris .
