Astronomy HOMEWORK Chapter 1 9th ed 5. In Figure 1-8, what is another name for the “Sun’s annual path?” Ecliptic. This term also refers to the mathematical plane of Earth’s orbit. 10. By about how many degrees does the Sun move along the ecliptic each day? The Sun moves 360 degrees in 365.25 days along the ecliptic, so Degrees per day = (360◦ )/365.25 days = 0.986◦ = 1◦ . Round to 1 degree since the question says “about how many...” 14. What are the vernal and autumnal equinoxes? What are the summer and winter solstices? How are these four events related to the ecliptic and the celestial equator? The equinoxes are the points on the celestial sphere where the ecliptic and celestial equator intersect. The vernal equinox is the point where the sun crosses the celestial equator northbound.…
Nine were found when Uranus passed in front of a bright star, the rings causing the star to temporarily disappear when they passed in front of it. This was the first time astronomers had detected rings around any planet other than Saturn. It was the first time, also, that astronomers had detected thin rings around any planet. The other two rings were found when Voyager 2 passed by.…
The region of our solar system between Mercury and Mars has very few asteroids, while the region between Mars and Jupiter has many asteroids. Based on what you have learned, what is the most likely explanation for the lack of asteroids between Mercury and Mars?…
A) As a planet orbits the sun, it sweeps out equal areas in equal time.…
F. Why are there no gas giant planets located between the Sun and asteroid belt?…
The question is should NASA fund asteroid studies? I think they should fund the asteroid studies because it could help us move to other places, it could save lives by building inventions that capture the asteroids, along with us trying to see if they have valuable resources. I believe it could help with protection, lifestyles and resources. The reasoning for these things is to help us out incase we try to move to a different places in our solar systems such as Mars. We could also try to build stuff that lets us go further in space. We could also find other life if NASA funds the mission like plants of life that could be similar to us.…

Pluto is a dwarf planet orbiting the Sun, with about a sixth of the mass of the Moon and a third of its volume. Like other Kuiper belt objects, which are generally outside Neptune's orbit, Pluto is primarily rock and ice. It has an elongated and highly inclined orbit that takes it from 49 astronomical units (7.4 billion km) away from the Sun down to 30, closer than Neptune. Light from the Sun takes about 5.5 hours to reach it at its average distance. Since its discovery in 1930, it had been considered the ninth planet, but the International Astronomical Union came up with a new definition for planets in 2006 that excluded Pluto after many other similar icy objects were found, including Chiron and Eris. Pluto has five known moons: Charon (about…
Our launch vehicles are no powerful enough to send massive spacecraft directly to the giant planets, so they must take circuitous paths returning to Earth or even traveling inward to Venus for gravity assists to boost momentum enough to send them beyond the asteroid belt. Rendezvousing with asteroids and comets can be even more challenging; they lack sufficient mass to brake fast-moving spacecraft into orbit, so the ships must perform years of orbit adjustment to match position and velocity with the tiniest worlds.…
They are formed by the impact of chunks of interplanetary matter (meteorites) striking the surface.…
The kuiper belt is a faraway region, further than neptune made from the left over particles that the planets left over when forming. It consists of many dwarf planets, asteroids, comets and any ice figured…
Many issues have arisen from the debate whether or not Pluto is a planet. Some astronomers say that Pluto should be classified as a "minor planet" due to its size, physical characteristics, and other factors. On the other hand, some astronomers defend Pluto's planet status, citing several key features.…
The narrator's first cat's name Pluto is that of the Roman God of the underworld. Pluto contributes to a strong sense of Hell and may even symbolize the Devil himself. Onyx cats have long been connected to bad luck and misfortune. The narrator's wife even joking mentions that black cats are said to be witches in guise. From this one can assume that a horrible thing will be bestowed upon the narrator, though one might believe it will be directly from Pluto, it happens indirectly. This can be tied with mankind being sinful and tainted by the Devil, for the narrator takes the Pluto as a dear companion and ends up falling from grace and being succumb with alcohol, violence and a lack of conscience.…
Outside the Earth, just as intriguing a process is occurring: the orbiting of a copious amount of debris around Earth. The NASA Orbital Debris Program Office defines debris as “all man-made objects in orbit about the Earth, which no longer serve a useful purpose.” Examples of such, include: decrepit fragments of spacecraft, upper stages of launch vehicles, debris created as a result of explosions or collisions and solid rocket motor…
