Answer: 937 systems
Question 5: Based the preliminary information in the simulation, what are the four
methods that can be used to detect planets around other stars?
Answer: transit, radial, telescopic, and astrometric techniques
Question 6: Based on this same information, which method has been the least
effective?
Answer: At times, it may be too bright to view clearly, therefore use a telescope or an
astrometric telescope. since it states that no exoplanet has been discovered, it is
astrological
Question 7: Which planet produced the greatest motion of the Sun in the simulation on
the
Detections
page?
Answer: Jupiter
Question 8: Where was the center of mass of the Sun-Jupiter-Saturn system – relative
to the Sun – when you ran the sim with Jupiter and Saturn selected?
Answer: Around the sun
