Astronomers have discovered a new planet around a nearby Sun-like star. The following data on the planet is known. It has a density of 3.7 relative to water along with a mass of 8x1023 kg and a radius of 4,200 km, and its orbital period is 1.3 years. a) From this information determine the following: the mass and radius of the planet relative to Earth, semi- major axis of the planet's orbit, as well as the mass of the host star. (Note: To find the relative value of any quantity take a ratio of the new value to the comparison value, for example in this case the comparison values are Earth's) b) From the information given and derived in part a), determine what type of planet this new discovery is and in which part of its solar system it lives. c) Given what we discussed in class about planetary atmospheres, predict what kind of atmosphere this planet will have.

Transcribed Image Text:Astronomers have discovered a new planet around a
nearby Sun-like star. The following data on the planet is
known. It has a density of 3.7 relative to water along
with a mass of 8x1023 kg and a radius of 4,200 km, and
its orbital period is 1.3 years.
a) From this information determine the following: the
mass and radius of the planet relative to Earth, semi-
major axis of the planet's orbit, as well as the mass of the
host star. (Note: To find the relative value of any
quantity take a ratio of the new value to the comparison
value, for example in this case the comparison values are
Earth's)
b) From the information given and derived in part a),
determine what type of planet this new discovery is and
in which part of its solar system it lives.
c) Given what we discussed in class about planetary
atmospheres, predict what kind of atmosphere this
planet will have.
