Question
I really need help with numbers 8 and 11 of this lab. I realy have tried to answer but i am not sure.
Note: This is Astronomy.
Equatorial System and Star Charts Examine the rectangular star maps. It represents a portion of the celestial sphere as a rectangle. Distortions occur when a 3D sphere is drawn as a flat rectangle. The distortions are severe near the top and bottom of the map. The distortion is quite workable for most purposes in the center two-thirds of the map. It's similar to the rectangular maps of the Earth that grossly distort the landmasses near the north and south poles, but work fine for the major populated areas closer toward the equator. The line running horizontally through the center of the star map represents the celestial equator. Right Ascension (RA) is measured along this line from right to left in units of hours and minutes. Notice the RA scale at the bottom of the map. Declination (Dec) is measured in degrees perpendicular to the celestial equator. The scales are on the left and right edges of the map. Print out a copy of the star chart. 1. Find on the map the "topmost" star of the constellation Libra a. What is its Right Ascension in hours and minutes? 15m b. What is its Declination in degrees?90 The sun's location at the first day of each season in the northern hemisphere is given in the table below. Plot its position on the rectangula star map for each date and label it with the 2. season.

Part 8
The orbits of the planets are all more or less in the same plane (called the ecliptic and defined by the plane of the Earth's orbit).
Part 11
The Moon's orbit about the Earth lies in a plane which is tilted by about 5.15° with respect to the plane of the Earth's orbit about the Sun on an average.
