I am trying to plot the ground tracks of an orbit. But I am having a problem with finding the longitude. The equation for the longitude is shown in the image. Is the Theta GMST initially zero because the greenwich meridian points to the Aries point (x-axis). How do you calculate alpha or vernal equinox? I saw a formula for alpha which is alpha = arctan(ry/rx), but the formula was for Right Ascension angle. Is the right ascension angle the same as vernal equinox. If not, then what is the formula for vernal equinox.
Description: If you could see both the Sun and the other stars during the day, this is what the sky would
look like looking south at noon on January 1 for an observer in the northern hemisphere. The Sun would
appear in the sky next to the more distant stars in the constellation Sagittarius, (labeled constellation C).
Also shown are other constellations (named and labeled A, B, D, and E) that will be visible above the
horizon at this time when facing south.

In your own words, describe the difference between apparent magnitude and absolute
magnitude. Explain the relationship between apparent magnitude, absolute magnitude and
distance.

- As we discuss in class, the radius of the Earth is approximately 6370 km. Theradius of the Sun, on the other hand, is approximately 700,000 km. The Sun is located,on average, one astronomical unit (1 au) from the Earth. Imagine that you stand near Mansueto Library, at the corner of 57th and Ellis.Mansueto’s dome is 35 feet (10.7 meters) high. Let’s imagine we put a model of theSun inside the dome, such that it just fits — that is, the model Sun’s diameter is 35 feet The nearest star to the Solar System outside of the Sun is Proxima Centauri,which is approximately 4.2 light years away. Given the scale model outlined above,how far would a model Proxima Centauri be placed from you? Give your answer inmiles and kmarrow_forwardConsider two identical stars, A and B.
