In turn, Earth and the other planets orbit the Sun. The space directly above our atmosphere is filled with artificial satellites in orbit. We examine the simplest of these orbits, the circular orbit, to understand the relationship between the speed and period of planets and satellites in relation to their positions and the bodies that they orbit. Circular Orbits As noted at the beginning of this chapter, Nicolaus Copernicus first suggested that Earth and all other planets orbit the Sun in circles. He further noted that orbital periods increased with distance from the Sun. Later analysis by Kepler showed that these orbits are actually ellipses, but the orbits of most planets in the solar system are nearly circular. Earth’s orbital distance from the Sun varies a mere 2%. The exception is the eccentric orbit of Mercury, whose orbital distance varies nearly 40%. Determining the orbital speed and orbital period of a satellite is ...

Space Briefing Book: Types of Orbits Written by: Space Foundation Editorial Team There are several types of Earth orbit, and each offers certain advantages and capabilities. Low Earth Orbit (LEO) LEO is commonly used for communication and remote sensing satellite systems, as well as the International Space Station (ISS) and Hubble Space Telescope. Medium Earth Orbit MEO is commonly used for navigation systems, including the U.S. Global Positioning System (GPS). A depiction of LEO and MEO. Credit: The Space Foundation Geosynchronous Orbit (GSO) & Geostationary Orbit (GEO) Objects in GSO have an orbital speed that matches the Earth’s rotation, yielding a consistent position over a single longitude. GEO is a kind of GSO. It matches the planet’s rotation, but GEO objects only orbit Earth’s equator, and from the ground perspective, they appear in a fixed position in the sky. GSO and GEO are used for telecommunications and Earth observation. A depiction of GSO/GEO.

Sun-Synchronous Orbit (SSO) A type of polar orbit, SSO objects are synchronous with the sun, such that they pass over an Earth region at the same local time every day.

The nucleus of an atom contains protons, neutrons, and electrons. While protons and neutrons make up the center of the nucleus, electrons can be found orbiting the nucleus, much like the planets orbit the sun. The circular path these electrons follow while orbiting the nucleus is known as the shell. Electrons in the same shell share the same energy level. Each shell consists of a subshell. There are four subshells: s, p, d, and f. Each subshell contains one or more orbitals. Orbitals are areas within atoms that have the highest probability (90%) of containing electrons. Orbitals are always designated with a number and a letter, starting at 1s. Shells and Orbitals The earth and other planets revolve around the sun. In the same way, we can compare the sun to the nucleus of an atom, and the planets revolving around it as electrons. However, unlike the planets revolving around the sun, the electrons don't strictly follow a set path around the nucleus. Electrons move in every direction, but they are limited to their own area, or the orbit that the electron follows, which is what we call shells, as illustrated in this figure. Shells around the nucleus are occupied by electrons Each shell, n, is labeled as a number, and is numbered 1, 2, 3, 4, etc. The number increases as each shell gets further away from the nucleus. These numbers represent energy level, n. These energy levels increase as it gets farther from the nucleus, so the higher the n, the higher the energy. Shells are di...

The traditional orbital elements are the six Keplerian elements, after When viewed from an secondary. The primary does not necessarily possess more mass than the secondary, and even when the bodies are of equal mass, the orbital elements depend on the choice of the primary. Two elements define the shape and size of the ellipse: • e)—shape of the ellipse, describing how much it is elongated compared to a circle (not marked in diagram). • a) — the sum of the Two elements define the orientation of the • i) — vertical tilt of the ellipse with respect to the reference plane, measured at the i in the diagram).

For example, to view the eccentricity of the planet Mercury ( e = 0.2056), one must simply calculate the Etymology [ ] The word "eccentricity" comes from eccentricus, derived from ἔκκεντρος ekkentros "out of the center", from ἐκ- ek-, "out of" + κέντρον kentron "center". "Eccentric" first appeared in English in 1551, with the definition "...a circle in which the earth, sun. etc. deviates from its center". [ citation needed] In 1556, five years later, an adjectival form of the word had developed. Calculation [ ] The eccentricity of an orbit can be calculated from the e = | e | where a is the length of the the geometric-average and time-average distance. :24–25 [ failed verification] e = r a − r p r a + r p = r a / r p − 1 r a / r p + 1 = 1 − 2 r a r p + 1 where: • r a is the radius at • r p is the radius at The eccentri...

The electrons in an atom are arranged in shells that surround the nucleus, with each successive shell being farther from the nucleus. Electron shells consist of one or more subshells, and subshells consist of one or more atomic orbitals. Electrons in the same subshell have the same energy, while electrons in different shells or subshells have different energies. Created by Sal Khan. An orbital is a space where a specific pair of electrons can be found. We classified the different Orbital into shells and sub shells to distinguish them more easily. This is also due to the history when they were discovered. Start with the easy. Imagine shells around the nucleus, that get bigger and bigger. The smallest, nearest to the nucleus is shell number 1. It's the one with the lowest energy. Then comes shell number 2, and so on. Now let's have a look at each shell in detail. They are decided into several subshells. They are the different kinds of orbital. So in the first shell there is only one subshell, the s orbital. It is called 1s. In the second shell there are s and p orbitals. But the 2s is of course further away from the nucleus, because it is in the second shell. Them comes the third shell even further away from the nucleus. In the third shell we again find p and s orbitals. The 2p orbital is closer to the nucleus than the 3s orbital, because it is in the second shell, which is closer to the nucleus than the third shell. What I understood is that the notation basically tells you...
