- If there was a planet orbiting a first generation star, which planet in our solar system would it resemble most? Would it be likely for such a planet to have life?If you stood on Earth during its formation, during which it captured about 1.6 ✕ 1011 particles per second, and watched a region covering 170 m2, how many impacts would you expect to see in an hour? (Notes: The surface area of a sphere is 4?r2. Hint: Assume that Earth had its current radius of 6,378 km.)The Solar Nebula model introduces the concept of ‘frost line’. Where are asteroids and comets found with respect to this frost line? How is their location connected to their composition?
- Out of the inner planets in the solar system (Mercury, Venus and Mar) which do you think is the most likely to be colonized? Explain why?Imagine that you visit a planet orbiting another star and discover that it is heavily cratered, but its small moon is nearly crater free. Why would that be a surprise? Speculate what might have happened to those objects.The transit method is used to detected exoplanets by measuring the reduced starlight caused by the planet passing in front of its host star. Say you measure multiple transits of the same exoplanet. What does the time in between the transits represent? Group of answer choices - Orbital period - Semi-major axis - Ecentricity - Planet's mass
- In the Transit method for detecting exoplanets, how many dips of light from the star need to be detected for it to be a successful detection of an exoplanet?If you were to record the spectrum of Saturn as well as the A ring, you would find light from one edge of the rings redshift and light from the other edge blueshift. If you observed a spectral line at a wavelength of 525 nm, what difference in wavelength (in nm) should you expect between the opposite edge of the rings? (Hint: The radius of the edge of the A ring is 136,500 km. Use the formula for orbital velocity and the formula for the Doppler shift.) _______ nmA newly discovered star was found to have a surface temperature of approximately 5185 K. If an astrologist wanted to look for potentially habitable planets, what is the maximum distance from the star to reach its solar system's 'Goldilocks Zone'?
- For the following light curve, which of the answers best illustrates the orientation of the exoplanet and its host star during the dip at Time 3? Light curve Time 1 Time 2 Time 3 Time 4 Choose one: А. O C. D. Intensity B.why do scientists generally think that liquid water is necessary for the origin of life? (astronomy)Planetary migration is a new process that has been added to the nebular theory of solar system formation. What type of planet, that does not exist in our solar system, made this change to the theory necessary? super-Earths Jovian planets beyond the "frost line" mini-Neptunes O hot Jupiters terrestrial planets in the habitable zone
