You are in a car 54.9 meters away from a street sign (distance from your face to the sign). The text letters on the street sign are 15.2 cm tall. What is the visual angle of the street sign letters in arc minutes?
The nearest star to our sun is Proxima Centauri, at a distance of 4.3 light-years from the Sun. A light-year is the distance that light travels in one year (365 days). How far away, in kilometers, is Proxima Centauri from the Sun?Express your answer using two significant figures.
Consider a star at a distance of 100 light years from the Earth and is moving
relative to the Earth at a constant velocity of 70000 km/hr perpendicular to its line
of sight from the Earth. What is the change of its angular position on our sky
when viewed by us now and by the ancient Egyptian 6000 years ago? Ignore all
other effect, e.g., the axial precession of the Earth.

- In countries at far northern latitudes, the winter months tend to be so cloudy that astronomical observations are nearly impossible. Why can’t good observations of the stars be made at those places during the summer months?arrow_forwardI 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.arrow_forwardGiven the location of Springfield, IL is 40N and 90W, answer the following questions.

- 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.
