I am struggling to answer this question. There are two parts to this question (as shown in the picture) I have already tried the answers 6.29x10^-13 for part 1 and 65.53 for part 2 and they are both incorrect. Any help is greatly appreciated, thank you!!
A halo CME is observed moving away from the Sun. Should we expect this CME to impact Earth? Provide a brief justification for the answer.
consider plutos diameter and mass. (2374)km & (1.303E22kg) and day which is 6.4 dayz long.
FIND: 1. please elaborate how would you get the answer to the escappe vel0city from plut0. 2. we would need to find the minimum energy required for an aircraft or ship of some sort with mass (525kg) to escape this planet.. 3. we would also need to find the t0tal energy for a complete orbit around the planet with an airship with a same mass (525) and an altitude of 224 km

- Imagine a telescope was placed on the planet Mercury and was used to measure the positions of stars in the sky. Assuming Mercury follows a circular orbit with a semi-major axis = 0.387 AU and a period = 88 days, calculate the maximum %3D stellar aberration that would be detected, expressing your answer in arcseconds. Choose the option below that best matches your answer. Select one: Оа. 100 O b. 25 О с 60 O d. 15 O e. 33arrow_forward6.. Determine the mass, radius, and orbital radius of this planet. help pleasearrow_forwardasap 1. Imagine that an object is moving around the Sun. What will be the orbital period of the object in Earth years if its orbit has a semi-major axis 1.587 AU?arrow_forward
- G:06)arrow_forwardDo the previous problem again, this time using the information that the Sun is 150,000,000 km away. You will get a very large number of km as your answer. To get a better feeling for how the distances compare, try calculating the time it takes light at a speed of 299,338 km/s to travel from the Sun to Earth and from Alpha Centauri to Earth. For Alpha Centauri, figure out how long the trip will take in years as well as in seconds.arrow_forwardThe Sun was once thought to be a planet. Explain why.arrow_forward
- How do we know the age of the Sun?arrow_forwardSuppose we find an Earth-like planet around one of our nearest stellar neighbors, Alpha Centauri (located only 4.4 light-years away). If we launched a "generation ship" at a constant speed of 1500.00 km/s from Earth with a group of people whose descendants will explore and colonize this planet, how many years before the generation ship reached Alpha Centauri? (Note there are 9.46 ××1012 km in a light-year and 31.6 million seconds in a year.arrow_forwardIn a globular cluster, astronomers (someday) discover a star with the same mass as our Sun, but consisting entirely of hydrogen and helium. Is this star a good place to point our SETI antennas and search for radio signals from an advanced civilization? Group of answer choices No, because such a star (and any planets around it) would not have the heavier elements (carbon, nitrogen, oxygen, etc.) that we believe are necessary to start life as we know it. Yes, because globular clusters are among the closest star clusters to us, so that they would be easy to search for radio signals. Yes, because we have already found radio signals from another civilization living near a star in a globular cluster. No, because such a star would most likely not have a stable (main-sequence) stage that is long enough for a technological civilization to develop. Yes, because such a star is probably old and a technological civilization will have had a long time to evolve and develop there.arrow_forward

I need help! Thank you!arrow_forwardThe Sun is moving at 220 ??/? around the Galactic Center at a more-or-less constant distance of 8.5 ???. To appreciate how remarkable this is, consider the following questions: a) How massive would the Sun have to be for the Earth to have an orbital velocity of 220 km/s at 1 AU? b) How fast would the Earth move if it was in orbit around the Sun at a distance of 8.5 kpc? Of course, you may ignore the effects of all other stars in this calculation.arrow_forward
