Unlike other schemes, this definition includes the objects with major semi-axis less than 39. 4 AU ( 2: 3 resonance ) – named Inner classical belt, or more than 48. 7 ( 1: 2 resonance ) – named Outer classical belt while reserving the term Main classical belt for the orbits between these two resonances.

Figure 1: Illustration of Johannes Kepler | Kepler's three laws with two planetary orbits.

Those NEOs that are asteroids ( NEA ) have orbits that lie partly between 0. 983 and 1. 3 astronomical units away from the Sun.

The special case of 1: 1 resonance ( between bodies with similar orbital radii ) causes large Solar System bodies to eject most other bodies sharing their orbits ; this is part of the much more extensive process of clearing the neighbourhood, an effect that is used in the current definition of a planet.

Parabolic trajectory | Parabolic ( 1 ) and Hyperbolic trajectory | hyperbolic ( 3 ) orbits are escape velocity | escape orbits, whereas elliptical and circle | circular orbits ( 2 ) are captive.

While the majority of plutinos have low orbital inclinations, a substantial number of them follow orbits similar to that of Pluto, with inclinations in the 10 – 25 ° range and eccentricities around 0. 2 – 0. 25, resulting in perihelia inside ( or close to ) the orbit of Neptune and aphelia close to the main Kuiper belt's outer edge ( where objects have 1: 2 resonance with Neptune ).

Pioneer 7 and Pioneer 8 are in solar orbits with 1. 1 AUs distance to the Sun.

* February 1 – Belgian astronomer Jean Meeus ( b. 1928 ) asserts that the orbits of all the planets of the Solar system were within the same 90 ° arc of the solar system on this date.

The special case of 1: 1 resonance ( between bodies with similar orbital radii ) causes large Solar System bodies to clear the neighborhood around their orbits by ejecting nearly everything else around them ; this effect is used in the current definition of a planet.

It orbits Jupiter at a distance of ~ 128, 000 km ( 1. 79 Jupiter radii ) within the planet's main ring.

For example, there are very few asteroids with semimajor axis near 2. 50 AU, period 3. 95 years, which would make three orbits for each orbit of Jupiter ( hence, called the 3: 1 orbital resonance ).

* 1961 – Vostok 1, the first manned space mission, designed by Sergey Korolyov and Kerim Kerimov, makes two orbits around the Earth

The bifurcation diagram nicely shows the forking of the possible periods of stable orbits from 1 to 2 to 4 to 8 etc.

Following a series of phasing orbits, the Star 30 solid rocket motor was used to perform an injection maneuver on August 15, 2002 to put CONTOUR in the proper trajectory for an Earth flyby in August 2003 followed by an encounter with comet Encke on 12 November 2003 at a distance of 100 to 160 km and a flyby speed of 28. 2 km / s, 1. 07 AU from the Sun and 0. 27 AU from Earth.

After 18 orbits, Soyuz 1 fired retrorockets and reentered the Earth's atmosphere.

Unfortunately, problems with the early version of the launch vehicle left Ranger 1 and Ranger 2 in short-lived, low-Earth orbits in which the spacecraft could not stabilize themselves, collect solar power, or survive for long.

137 radio transmissions and 277 orbits of the Moon were completed before the batteries failed on 1 October 1966.

All four types of message listed in Table 1 are permitted, although decorum and cocktail tradition require holding the commands to a minimum, while exclamations having complimentary intonations are more than customarily encouraged.

Of types of message listed in Table 1, commands and statements are the only ones sent through the vertical network shown in Figure 3.

If we are to believe the list of titles printed in Malraux's latest book, La Metamorphose Des Dieux, Vol. 1 ( ( 1957 ), he is still engaged in writing a large novel under his original title.

And if the foreigners fighting in the Katanga Army are mercenaries then Lafayette and Von Steuben were mercenaries too, as were also the members of the Lafayette Escadrille in the early part of World War 1, and of Chennault's Flying Tigers in the early days of World War 2.

The reasons are obvious: ( 1 ) the state is buying in quantity, and ( 2 ) it has no federal excise or state sales tax to pay.

Taxation of tangible movable property in Rhode Island has been generally of a `` hands off '' nature due possibly to several reasons: ( 1 ) local assessors, in the main, are not well paid and have inadequate office staffs, ( 2 ) the numerous categories of this component of personal property make locating extremely difficult, and ( 3 ) the inexperience of the majority of assessors in evaluating this type of property.

Among the many problems in the taxing of personal property, and of movable tangible property in particular, two are significant: ( 1 ) situs, ( 2 ) fair and equitable assessment of value.

Since accurate base maps are necessary for any planning program, the first step taken by the planning division to implement the long-range state plan has been to prepare two series of base maps -- one at a scale of 1 inch to a mile, and the second a series of 26 sheets at a scale of 1 inch to 2000 feet, covering the entire state.

The mapping of important physical features such as slopes and types of soil and the collection of all available information pertaining to public utility service areas are being conducted as staff projects and, like the other two inventory projects, are scheduled for completion July 1, 1961.

Included in the findings are: 1.

The adjustments needed to establish a uniform and coordinated fiscal tax collection year calendar throughout Rhode Island, based on a July 1 to June 30 year, are shown below.

Six cities and towns are presently on a July 1 to June 30 fiscal year and have coordinated their tax collection year with it.

Six cities and towns are now on a July 1 to June 30 fiscal year and will need only to adjust their tax collection year calendar to establish uniformity.

Assuming an adjustment to the July 1 to June 30 fiscal year, the required adjustment of the tax collection years and the towns involved are shown in Table 3.

There are hereby created in the Treasury of the United States ( 1 ) a special fund to be known as the Yugoslav Claims Fund ; ;

Important considerations common to each type of shelter are: 1.

We have concluded that petitioner's claims are controlled by the rationale of Gonzales v. United States, 348 U.S. 407 ( 1955 ), and United States v. Nugent, 346 U.S. 1 ( 1953 ), and therefore affirm the judgment.

The wildlife habitat management proposals for the 10-year period are: 1.

Program proposals for forest development roads and trails for the 10-year period 1963-1972 are as follows: 1.

The two Governments agree that the issuance of purchase authorizations for wheat and rice providing for purchase after June 30, 1961, shall be dependent upon the determination by the United States Government that these commodities are in surplus supply and available under Title 1, of the Act at that time.

Specifically, the conceptual diagram graph 1 identifies only three boxes, two ellipses, and four arrows ( and their five labels ), whereas the picture 1 shows much more pictorial detail, with the scores of implied relationships as implicit in the picture rather than with the nine explicit details in the graph.

Special cases of this are circular orbits ( a circle being simply an ellipse of zero eccentricity ) with the planet at the center, and parabolic orbits ( which are ellipses with eccentricity of exactly 1, which is simply an infinitely long ellipse ) with the planet at the focus.
