Welcome to McBride's Resource Page for your Constellation Projects!//**

Sun = 1) ||  ||~ Average Luminosity (The Sun = 1) ||   ||~ Main Characteristics ||   ||~ Examples || The constellation project is your chance to shine! Each of you has been given a constellation that you will research. You will collect data, organize it and present it to the class. A rubric will be distributed that describes what each level of achievement involves. Your project must, at a minimum, include the following:
 * ~ = 1) ||  ||~ Average Radius (The [[image:radec_ra_decl_anim.gif width="545" height="323" align="left"]]

List of the star names that make up your constellation. You will also need the star types, temperatures and solar masses of these stars.

A Diagram of your Constellation

The season it is most visible at 10 p.m. from Enola.

A description of the mythology surrounding your constellation.

A list of the deep sky objects that are associated with your constellation. These would include Messier Objects and NGC objects. (these are the cool things!) Pictures of these objects on your page will get you the best grade!


 * Definitions:

Messier Deep Sky Objects**: any object that begins with the letter M, discovered by Charles Messier when he was looking for comets. There are now 110 Messier objects.


 * NGC Objects**: objects identified and listed in the New General Catelogue. There are thousands of NGC objects.


 * Spectral Class of Stars**: O B A F G K M, which we all now know classifies stars according to their color and temperature.
