- If the velocity of the Solar Wind about 4.0 x 10^2 km/s and the visible tail of a comet of 9.0 x 10^8 km long, how many days does an atom in the solar wind take to travel from the nucleus to the end of the visible tail? (note: 1 day= 86,400 sec) _______ daysWhat is the evidence that suggests asteroids might have geologically active surfaces?_____ km/s ______ hr
- Suppose you could chose any one moon in our solar system to visit. Which would you pick and why? Moons of the Solar System Scaled to Earth's Moon Earth Mars Asteroid Jupiter Saturm Uranus Neptune Pluto Plukes uck Charen Mranda Triten EncelaunAt what average distances (in AU) from the Sun would you expect to find Kirkwood gaps where the orbital period of asteroids are respectively four-ninths, and three-sevenths, of the orbital period of Jupiter? (Hint: use Kepler's third law.) inner gap at_______ AU outer gap at_______ AUThe 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
