This simulation-based module introduces the Horizon Coordinate system and the Equatorial Coordinate system of mapping the sky. The relationship between the two coordinate systems is explicitly explored. Students can change the rate of rotation, the position of the observer, and add or delete stars in the sky. Instructor resources are available including student manuals, assessment materials, and a list of the assumptions used.
Editor's Note:The Horizon Coordinate system is defined with respect to an individual observer standing on the earth. The Equatorial Coordinate system maps celestial objects by projecting the Earth's geographic poles and equator onto the celestial sphere. Both systems have advantages/disadvantages, and this module explores each.
This is part of a collection of astronomy applets.
