Though Titan has a small mass , it is able to retain an atmosphere because it - correct answer very cold A bit of matter that enters Earth's atmosphere and survives to reach the ground is called - correct answer a meteorite Pluto is no longer classified as a planet; instead it is classified as a(n) ____________________. - correct answer dwarf planet The impact of a large asteroid comet with Earth has been proposed to have caused the extinction of the dinosaurs. The impact site of this comet is in or near - correct answer Chicxulub, Mexico The largest satellites of Jupiter are known as the ____________________ satellites. - correct answer Belt and zone circulation - correct answer occurs on Jupiter. occurs on Saturn. is caused by rising and sinking gases. is more obvious on Jupiter than on Saturn. all the above The region of Jupiter that is responsible for the magnetic field is composed of ____________________. - correct answer A(n) ____________________ is produced when Earth passes through the debris left by a comet as it passed through the inner solar system. - correct answer meteor shower Our Solar System is likely unique among the stars in our galaxy. - correct answer False When we detect light from an object that is moving rapidly away from us, that light appears to be . When we instead detect light from an object that is moving rapidly towards us, that light appears to be . - correct answer Why is a very hot star not a good candidate to find life? - correct answer Because its lifetime is too short for life to evolve. Astronomers want to find exoplanets because: - correct answer it helps them to understand how planetary systems form. An exoplanet and its star both appear to orbit the _______ as shown by the black dot in the photo below. - correct answer none of these star center of mass Why is a cold star not a good candidate to find life? - correct answer Because the habitable zone is very narrow. Examine the figure below. What method of looking for extrasolar planets requires the planet to pass in front of the star? - correct answer Transit method When astronomers began searching for extrasolar planets, they were surprised to discover Jupiter-sized planets much closer than 1 AU from their parent stars. Why is this surprising? - correct answer These planets must have formed at larger radius where temperatures were cooler and then migrated inward. The borderline between the most massive planet and the least massive brown dwarf occurs at: - correct answer 13 Jupiter masses Why have astronomers found more Jupiter-sized planets at a distance of 1 AU around other stars than Earth-sized planets? (select all correct answers) - correct answer A Jupiter-sized planet shines brighter than an Earth-sized planet. A Jupiter-sized planet exerts a larger gravitational force on the star than an Earth-sized planet, and the Doppler shift of the star is larger. blueshift and redshift - correct answer scientists determines if an object is moving away from the earth because the light from the object appears redder, and if the object is moving toward earth, the object appears blue Why have astronomers found more Jupiter-sized planets at a distance of 1 AU around other stars than Earth-sized planets? (select all correct answers) - correct answer A Jupiter-sized planet exerts a larger gravitational force on the star than an Earth-sized planet, and the Doppler shift of the star is larger. A Jupiter-sized planet occults a larger area than an Earth-sized planet. A Jupiter-sized planet shines brighter than an Earth-sized planet. The Doppler shift can be used to determine the __________ of an object. - correct answer radial velocity Detecting a planet around another star using the transit method is difficult because: - correct answer the planet must pass directly in front of the star Our Solar System is likely unique among the stars in our galaxy. - correct answer False Why is a very hot star not a good candidate to find life? - correct answer Because its lifetime is too short for life to evolve. What method of looking for extrasolar planets requires the planet to pass in front of the star? - correct answer Transit method The habitable zone around a star depends most on the star's: - correct answer temperature and size Most planets currently found around other stars are: - correct answer comparable in mass to Neptune or more massive Which of the following is evidence for the connection between comets and meteor showers? - correct answer Meteor showers are an annual event. Many of these are known to be when the Earth crosses a comet's orbit. The region of Jupiter that is responsible for the magnetic field is composed of ____________________. - correct answer liquid-metallic-hydrogen A(n) ____________________ is produced when Earth passes through the debris left by a comet as it passed through the inner solar system. - correct answer meteor shower In terms of mass, Jupiter is made mostly of - correct answer hydrogen and helium. The gas tail of a comet always - correct answer points away from the sun The fresh newly created surfaces of icy satellites of Jovian planets - correct answer appear very bright because fresh ice is very reflective.
