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.
