The same equation can be used with any astronomical coordinate system.
2.
Bernstein finds out that the astronomical coordinates given in the message represent where the Earth will be in 1998 due to the solar apex.
3.
When specifying coordinates on the Moon it should therefore always be mentioned whether geographic ( or rather selenographic ) coordinates are used or astronomical coordinates.
4.
An example of the use of signs as astronomical coordinates may be found in the " Nautical Almanac and Astronomical Ephemeris for the year 1767 ".
5.
A three-dimensional position is calculated using messages from four or more visible satellites and referred to the optical astronomy, combines astronomical coordinates and the local gravity vector to get geodetic coordinates.
6.
Unless you want to look at one of a predefined set of obscurely named objects, Real Sky View requires you to identify the astronomical coordinates of a field of interest to be able to look at it.
7.
Throughout their many centuries of use, which continues today for specialized topics such as time, angles, and astronomical coordinate systems, sexagesimal notations have always contained a strong undercurrent of decimal notation, such as in how sexigesimal digits are written.
8.
In astronomy, a given point on the celestial sphere ( that is, the apparent position of an astronomical object ) can be identified using any of several " astronomical coordinate systems ", where the references vary according to the particular system.
9.
The most recent modification was made on May 12, 1992, with the addition of four stars to the celestial globe ( representing states created between 1982 and 1991 ), and a slight change in the stars'positions was made to match the astronomical coordinates correctly.
10.
While such context-dependent representations of numeric quantities are easy to critique in retrospect, in modern time we still have " dozens " of regularly used examples ( some quite " gross " ) of topic-dependent base mixing, including the particularly ironic recent innovation of adding decimal fractions to sexagesimal astronomical coordinates.
