Description
If you observed the solar system from the nearest star (distance 1.3 parsecs), what would the maximum
angular separation be between Earth and the sun? Note that 1 pc is 2.1 105 AU. (Hint: Use the small-angle
formula, Chapter 3.)
given:
the mass of Sagittarius A* in units of solar masses = 3,832,087.773 MSun.
Question:
This object is known to be relatively small in size, with a diameter of about 60 million kilometers. For comparison, Earth is 149.6 million kilometers away from the Sun. Based on this fact, what do you think this object is? Hint: The object itself emits virtually no light at all.
If you could visit another planetary system while the planets are forming, would you expect to see the condensation sequence at work, or do you think that process was most likely unique to our Solar System? How do the properties of the extrasolar planets discovered so far affect your answer?
Do you expect the most planetary system in the Universe have analogs to our Solar System’s asteroid belt and Kuiper Belt? Would all planetary systems show signs of an age of heavy bombardment?
If the solar nebula hypothesis is correct, do you think there are more planets in the Universe than stars? Why or why not?

It is believed that each planet in our solar system began as its own nebula. Over time, a nebula becomes cooler and grows in size. The density of a nebula is greatest at the edges and least in the center. There are no nebulas left in our galaxy because they have all formed stars and planets. Over time, a star will form at the center of a nebula.arrow_forward
