- Re-order the numbers so the events occur in the correct order, with the oldest event as number 2, and the youngest event as number 13. 2. Now at roughly 100% of present-day mass and the asteroid bombardment over, Earth begins cooling and differentiating. As the outer layer of the Earth cools and solidifies, lighter elements and compounds rise to the surface while the denser ones sink to the core 3. The now differentiated ice, gas, and dust of the solar accretion disc conglomerates together into asteroids from gravity 4. "The Big Whack" A Mars-sized protoplanet we call Theia collides with primitive Earth, adding even more energy and mass 5. The Big Bang 6. As the early atmosphere cools, water vapor is eventually cool enough to condense into liquid water, eventually covering the planet in an ocean 7. The debris from the collision of Earth and Theia produce a ring in orbit. This ring eventually coalesces into the Moon, just as Earth coalesced from the solar accretion disc 8. A nebula…Originally thought to be the realm of comets, over the past two decades we discovered that the Kuiper Belt region hosts also many other objects similar in size to Pluto (Figure 22). This seems to imply that there are two completely different types of objects in the region. Do you think that both types of objects formed in this region, or some of these may have migrated to this region at a later time? Briefly explain your reasoning.4) Science fiction movies often portray asteroid belts as crowded, dense regions that require spaceships to maneuver quickly to get through them. In this problem, we will calculate the fraction of volume in an asteroid belt that is actually occupied by asteroids. a) If there are 300,000 large asteroids between 2 and 3 AU from the Sun, and each asteroid is assumed to be spherical with a radius of 100 km, determine the total volume occupied by asteroids in this region. Recall that the volume of a sphere is given by the equation V = 4TR³ /3. b) Let's assume the region in which these asteroids orbit is an annulus with an inner radius of 2 AU, an outer radius of 3 AU, and a thickness of 2Ro. Determine the volume of this region. Recall that the area of a circle is given by the equation A = TR². Here are two conversions that you'll need: 1 AU = 1.496 × 108 km and 1 Ro = 6.955 × 105 km. c) What is the ratio of the volume occupied by asteroids to the volume of the asteroid belt (i.e., the…
- Explain the light emission by meteorite?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.)A typical comet contains some 1013 kg of water ice. How many comets would have to strike Earth in order to account for the roughly 2×1021 kg of water presently found on our planet? (Hint: simple division) If this amount of water accumulated over a period of 500 million years, how frequently must Earth have been hit by comets during that time? (Hint: Calculate, on the average, how many comets hit the Earth per year during that time.)
- Due to the fact that planets emit more infrared radiation than any other type of light, astronomers have the best chance of directly imaging an exoplanet in the infrared part of the spectrum. select one of the following: A) true B) falseThe 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 massIn 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?
