The five figures below show an asteroid (on the left in each of the figures) interacting gravitationally with a a variety of objects. Considering only the two objects shown in each pair, rank the strength of the gravitational force acting on the asteroid on the left, from strongest to weakest.
This person is located at _____________ degrees N latitude.
The Summer Triangle (shown below) is comprised of stars from the constellations Aquila (Altair), Cygnus (Deneb), and Lyra (Vega). Thus, the Summer Triangle is
A light-year is a measurement of time.
We are used to seeing celestial objects in the sky and see them "move" across the sky and but we are not as familiar with describing their size or motions in terms of (arc)degrees, (arc)minutes, and (arc)seconds a.k.a angular size. A useful way to measure angular size is to use your outstretched arm and your hand/fingers (arm must be outstretched for this to work) as shown in the figure below.Now let us take a look at a real-life application of this technique. Our Moon can have a shift of about 2 degrees (with respect to the background stars) when it is observed from different locations. According to the figure shown, which is the closest estimate of that amount?
