Sorting Task: Comets, Meteors, and also AsteroidsPart AListed following are some distinguishing features of comets, meteors, and also asteroids. Complement these to the appropriate category that objects.

You are watching: Which of the following properties can be inferred from the star’s orbital period


\"*\"
Visual task Exploring the development of Comet StructuresA comet entering the inside solar system from afar will __________.form a coma and also some time later kind a tailDuring the moment that a comet passes with the inside solar system, the comet can appear quite bright because __________.sunlight shows off the comet’s tail and comaA comet’s plasma tail constantly points directly away indigenous the Sun due to the fact that __________.of press exerted by the fast-moving fee particles in the solar windVocabulary in Context: CometsPart AMatch the native in the left-hand column to the proper blank in the sentence in the right-hand column.

Ranking Task: simple Properties that Extrasolar PlanetsPart AThe adhering to images display four identical Sun-like stars and their companion planets, all traveling in one orbits. In each case, the massive of the world is provided in Jupiter masses and also the orbital distance is offered in expensive Units (AU). Rank each case based on the toughness of the gravitational pressure exerted by the extrasolar planet on its central star, native weakest come strongest. If girlfriend think that 2 (or more) diagrams must be ranked together equal, traction one on optimal of the other(s) to present this equality. (Not to scale)
\"*\"
Part BThe complying with figures present four identical Sun-like stars and also their companion planets. Each planet’s orbital distance is given in huge Units (AU); keep in mind that in this case, all 4 planets have actually the same mass. Location the extrasolar planets based on the lot of time it takes each to complete one orbit, native shortest to longest. (Not to scale)
\"*\"
Part CThe complying with images show the collection of four stars and planets together in component B. Imagine that an Earth-based observer might see the activity of every of the stars edge-on. Rank every star based on the amount of Doppler shift we’d see in its spectrum together it moves in response to the gravitational tug of its planet, from smallest to largest. (Not come scale)

Ranking Task: Velocity Curves for Stars v a single Orbiting PlanetPart AThe complying with four graphs present the velocities, toward and also away native Earth, of 4 identical stars. Assume that all four stars have extrasolar planets orbiting them in ~ the exact same distance, and that the velocities room inferred by measuring Doppler shifts in the spectra the the stars. Location the graphs native left come right based upon the amount of orbital Doppler shift observed in each star’s spectrum, from smallest to largest.
\"*\"
Part BThe adhering to four graphs show the velocities, toward and away from Earth, of 4 identical stars (the exact same graphs shown in part A). Assume the all 4 stars have extrasolar planets orbiting them in ~ the same distance. Rank the graphs indigenous left come right based upon the amount of time that it take away the extrasolar world orbiting every star to finish one orbit, indigenous shortest to longest. If girlfriend think that 2 (or more) of the graphs must be ranked as equal, drag one on height of the other(s) to present this equality.
\"*\"
Part CThe complying with four graphs present the velocities, toward and also away native Earth, of 4 identical stars (the very same graphs presented in components A and also B). Assume the all four identical stars have extrasolar planets orbiting them in ~ the very same distance. Rank the graphs native left come right based on themassof the extrasolar planet that orbits the star, from smallest to largest.

Visual Activity: Measuring properties of Extrasolar PlanetsWhich that the complying with properties have the right to be inferred indigenous the star’s orbit period?the planet’s orbital radiusIs it feasible to recognize the planet\"s mass indigenous the star\"s velocity curve?yes, by measure both the star\"s orbital period and its readjust in velocity end the orbitConsider the world that causes the stellar motion shown in Plot 2 (be certain you have actually clicked the “Plot 2” button in the lower window of the animation). What deserve to be said around a different planet orbiting the exact same star through an orbital period of 500 days?The planet should be closer to the star.--------------------------------------------------------------------------------------------------------------------What is the many important specifying property the the Trojan asteroids?They orbit the sun in the same path as Jupiter and also 60° front of and also behind it.Which the the complying with characterizes the Kuiper belt?It is a disk-like an ar between the external planets and also the Oort cloud.The ingredient of a usual comet\"s nucleus space most most likely ________.dust and also rocky corpuscle trapped in methane, ammonia, and water iceHow was Pluto discovered?It was an easy luck and hard work.Which the the complying with is NOT one of the criteria necessary to classify an object as a significant planet?It must have actually at least one moon orbiting around it.What is the source of the product of a meteor shower?CometsThe most common form of meteorite come strike earth is ________.rockyPlanetesimals were developed through what process?accretionWhich the the following objects is NOT finest explained by some sort of unique impact event?The asteroid beltWhich the the following methods have astronomers provided to finding extrasolar planets?Extrasolar planets have been recognize using every one of the methods noted here.Planetary transits, coupled with radial velocity measurements, can not unambiguously tell united state which that the following about an extrasolar planet?The planet\"s compositionIf we resided in a solar system outside of our own, would we have the ability to detect planet using Doppler dimensions of ours Sun\"s \"wobble\"?No. The Doppler shifts would be too small for united state to detect.What is a \"hot Jupiter?\"A earth with Jupiter\"s massive orbiting really close come its star.What is a brown dwarf?An object with much more mass than Jupiter, however not enough mass to come to be a star.What is a the best explanation because that the hot Jupiters?They formed much from your stars, and “migrated†inward due to the fact that of interactions v the gas disk indigenous which lock formed.
