Group Assignment #3
What is the name of the cloud of interstellar gas and dust that condensed to form the entire
solar system, including the sun and planets? -(correct answer)Solar Nebula Which of the
following statements is considered to be true? - The planets formed after an asteroid collided
with the sun. - The planets formed after two stars collided. - The planets formed when they
were captured by our sun as they passed by in interstellar space. - The sun and planets
formed from different clouds of gas and dust. - The planets formed from the same chunk of
cloud from which the sun formed. -(correct answer)The planets formed from the same chunk of
cloud from which the sun formed. What was the temperature (in Kelvin) at the location of the
Earth? ~2000 K ~1000 K ~600 K ~400 K ~100 K -(correct answer)~600 K What was the
temperature (in Kelvin) at the location of the Mars? ~2000 K ~1000 K ~600 K ~400 K ~100 K
-(correct answer)~400 K Which planets formed at temperatures hotter than the boiling point of
water? -(correct answer)Mercury, Venus. Earth, Mars Which planets formed at temperatures
cooler than the freezing point of water? -(correct answer)Jupiter, Saturn, Uranus, Neptune
Over what range of distances (in AU) from the Sun would you expect to find light gases, such
as hydrogen and helium, collecting together to form a Jovian planet? -(correct
answer)between 5 and 50 AU Early in the history of the solar system, when planets were being
assembled, could an Earth-like planet form at 10 AU? -(correct answer)No Early in the history
of the solar system, when planets were being assembled, could an Jupiter-like planet form
where Mercury formed? -(correct answer)No Over what range of distances from the Sun would
you expect to find only solid, rocky and metallic material collecting together to form a terrestrial
planet? -(correct answer)between 0.4 and 3 AU
