-Eccentricity- 100,000 year cycle of Earth’s orbit around the sun; refers to the shape or degree of stretching of the orbit…
4. Declination – the angular distance of a point north or south of the celestial equator…
Ecliptic - a plane in space defined by Earth’s orbit around the Sun; plane by which the orbit of all other planets in the solar system are compared…
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.…
3. The apparent westward "drift" of the planets compared to the background stars is called ______________. (Points: 2)…
2. A G2 I star is larger in diameter and more luminous than the sun.…
* Note how the Earth Map, Celestial Sphere, and Horizon Diagram are linked together. Grab the map cursor and slowly drag it back and forth vertically changing the observer’s latitude. Note how the observer’s location is reflected on the Earth at the center of the Celestial Sphere (this may occur on the back side of the earth out of view).…
My experience with this optional observation lab was a great experience overall, just as I had expected it to be. I was much more interested in participating in the observations versus sitting in a classroom every week and attending the labs like in 1010.…
Which of the following statements regarding the motion of stars in the celestial sphere is correct?…
8. In both Hipparchian and Ptolemaic systems, the planets are assumed to move in a small circle called an epicycle, which in turn moves along a larger circle called a deferent. Both circles rotate clockwise and are roughly parallel to the plane of the Sun's orbit (ecliptic). Despite the fact that the system is considered geocentric, the planets' motion was not centered on the Earth but on what is called the eccentric. The orbits of planets in this system are epitrochoids.…
The movements from east to west are the movements of the sun. East means beginning and west means the end.…
2. Celestial Equator: The great circle lying on the celestial sphere the plane of which is perpendicular to the line joining the north and south celestial poles…
Beck Anxiety Inventory (BAI) A part of the Beck Scales to assist the clinician in making balanced and reliable assessments of patients. Test results are useful as a first step in detecting and proper treatment of an affective disorder. The Beck Anxiety Inventory gauges the severity of patient anxiety. Beck Depression Inventory Assesses depression and, in conjunction with the Beck Hopelessness Scale (BHS), to gauge the likelihood of suicide.…
‘Earth is only eight thousand miles in diameter, which is almost a negligible dimension in the great vastness of space. Our nearest star - the sun - is ninety-two million miles away. The nearest star’ after that ‘is one hundred thousand times further. It takes approximately four and one-third years for light to get to us’ (Fuller: 1969: P1) It puts us into perspective. We are just one of nine planets in one of one hundred billion galaxies approximately. (1923: Other Galaxies Exist: no date)…
