11. Kepler’s second law helps to determine the ratio between Pluto’s velocity at aphelion and perihelion (va/vp). To determine this ratio, first calculate the area swept out by Pluto’s orbit. This area is approximately equal to the area of a triangle: area = 1/2 (distance to the sun) current velocity X time. If the area that the orvit weeps out in a fixed amount of time, such as 30 days, is the same at aphelion and perihelion, this relationship can be written. What is the ratio vp/va for…
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.…
When the mass of the sun is increased, the gravitational pull is greater. Therefore the orbit is smaller. When the mass of the sun is decreased, the orbit is larger.…
"An imaginary line drawn from the center of the sun to the center of the planet will sweep out equal areas in equal intervals of time." This law implies that when a planet is far away from the sun moves slowly and moves faster when it is closer to sun.…
Christopher Crokett in “Pluto: Explored” points out that the Planet Pluto has no control nor gravity. The description of Pluto is the diminutive ice-coated body and outlier. It always far above and well below the plane of the solar system. Moreover, Pluto once cross another planet’s like (Neptune’s) orbit.…
B) The closer a planet is to the sun, the slower it moves in its orbit.…
Address the following points about the two essays you read. Remember to explain your answers with specific examples from the essays.…
Why Pluto should stay a planet You may think that Pluto is all alone and the only lonely planet. He is really not left out. There are more Dwarf planets out there. Pluto is not alone!…
1) What do we mean by a geocentric universe? Contrast a geocentric view with our modern view of the universe.…
The inferior planets were always observed to be near the sun, appearing only shortly before sunrise or shortly after sunset. To accommodate this, Ptolemy's model fixed the motion of Mercury and Venus so that the line from the equant point to the center of the epicycle was always parallel to the earth-sun line.…
Good morning ladies and gentlemen. Today you are here to decide whether the defendant presented is insane. This man was imprisoned for murdering his wife. This was after killing his first cat and aiming to kill his second. Why kill so many innocent lives? After hearing his significant story, many of you must be confused. You may believe he is indeed insane while others may think he pretending to be crazy in order to get out of his death penalty. My job here is to prove that he is faking it all. Therefore, he deserves to die for his horrible actions.…
Pluto is different from the other planets because it is a dwarf planet and it’s far away from the other planets and the sun so that means it is also the coldest plant which is -400 degrees F .and as it states on the Nasa website that there are no known rings around Pluto’s atmosphere and if Pluto was a planet it’s would be the smallest plant In the solar system .the farthest away from the sun 248 year is going to delay.…
A solar eclipse is when the Sun is hidden behind the Moon; the Moon passes between the Sun and Earth, blocking the Sun from view. These only occur during a new moon, at which time the Moon is seen as a silhouette when passing infront of the Sun. There are total eclipses, where the Moon completely covers the Sun, and partial eclipses, where the Moon only covers part of the…
Objective: The objective of this lab assignment is todetermine if objects with different mass fall at the same rate or vatying rate in the presence of ar and in a vacuum.…
I called for Pluto as I fetched the leash from the parlor. He came running and leaped on top of me, "Down boy, I know you love our walks together and I do too, but you need to calm down." I put the leash on him and we ventured out...…
