Sentences with phrase «angular separation»
Angular separation refers to the measurement of the distance between two objects in space, usually stars or celestial bodies. It is the angle that is formed between the two objects when observed from a specific point, such as the Earth. The larger the angular separation, the farther apart the objects appear to be.

Abstract: In a search for common proper motion companions using the VISTA Hemisphere Survey and 2MASS catalogs we have identified a very red (J - Ks = 2.47 mag) late - L dwarf companion of a previously unrecognized M dwarf VHS J125601.92 - 125723.9, located at a projected angular separation of 8.06» + / -0.03».

However, the speckles formed at large angular separation are comparable to the intensity of the planet in the Keck - like design.
Gaia can do the same trick with Pluto and Charon, though it is a little more difficult because both bodies are moving with respect to each other and the spacecraft, slightly changing their angular separation.
