Question 1

What is the right ascension and declination for Polaris, the North Star?
◦ RA indeterminate, D 90 degrees
◦ RA 0 hr, D 80 degrees
◦ RA 0 hr, D 0 degrees
◦ RA 90 hr, D -90 degrees

Question 2

Earth hits its perihelion position in January. Solar radiation is proportional to the distance squared between the Sun and the earth, so why isn't it hot in "winter" at perihelion?
◦ The ellipticity of the orbit is small, so the affect is small; seasons are caused by tilt of Earth's orbit.
◦ It is; it is called summer in the Southern Hemisphere, and there is just a time lag for the Northern Hemisphere.
◦ Precession modifies the effect as Earth wobbles on its axis.
◦ None of these is correct.

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
