Parallax in a sentence

Diurnal parallax Diurnal parallax is a parallax that varies with rotation of the Earth or with difference of location on the Earth.

The solar parallax is related to the Earth–Sun distance as measured in Earth radii by : The smaller the solar parallax, the greater the distance between the Sun and Earth: a solar parallax of 15" is equivalent to an Earth–Sun distance of main Earth radii.

A more sophisticated calculation factors in a star's loss of mass over time. citation Spectroscopic parallax Spectroscopic parallax is another commonly used method for determining the distance to a binary system.

Astronomers had believed for some time that parallax would provide the first accurate measurement of interstellar distances—in fact, in the 1830s there was a fierce competition between astronomers to be the first to measure a stellar parallax accurately.

It also illustrates the important point that parallax need not be caused by any motion of the observer, contrary to some definitions of parallax that say it is, but may arise purely from motion of the observed.

Parallax in astronomy Parallax is an angle subtended by a line on a point.

Parallax in sights Parallax affects sights in many ways.

Parallax The new Hipparcos reduction of Rigel's parallax gives a distance of convert, with a margin of error of about 9%.

Some astronomers endeavoured to explain this by parallax, but these attempts were futile, for the motion was at variance with that which parallax would produce.

Some target and military style telescopic sights without parallax compensation may be adjusted to be parallax free at ranges up to 300 yd/m to make them better suited for aiming at longer ranges.

The diagram (above) for stellar parallax can illustrate lunar parallax as well, if the diagram is taken to be scaled right down and slightly modified.

The distance, is found from the following equation, : Where is the parallax, measured in units of arc-seconds. citation Dynamical parallax This method is used solely for binary systems.

The geocentric model, consistent with planetary parallax, was assumed to be an explanation for the unobservability of the parallel phenomenon, stellar parallax.

Can Green Lantern Move Past His Time as Parallax?

From Parallax's control to encounters with New Gods, some of the best Green Lantern stories exist within annual comics that celebrate the GL mythos.

Hal Jordan suffered a tragedy that led him to destroy the Green Lantern Corps and become the reality-bending villain Parallax during "Emerald Twilight" (by Ron Marz, Bill Willingham, Fred Haynes, and Darryl Banks).

Intrigued at the idea, Parallax removes his Power Ring and Oliver lays down his bow and arrows.

The RF5.2 mm F2.8 L Dual Fisheye, which won the bronze award, has two fisheye lenses and can shoot 3D 180-degree VR images using the parallax of left and right optical systems.

The cover image from the Criterion Collection version of The Parallax View, starring Warren Beatty.

The true nature of Parallax was soon revealed to Kyle Rayner by the last Guardian, Ganthet, and Kyle relays this information to Hal’s best friend, Oliver Queen, while Hal himself learns from the Spectre.
