Question
Below is a lab I could use help with, I want to compare my answers with someone else. This would help me verify if I understand what I am doing.
P.S. The question is #17 with subparts that includes a table
Lab : MAdjusting the Planets' Positions on the Orbital Charts [15 answers/22.5 pts] As you have seen, given the same number of days or years, each planet will move a varying amount in its orbit. Therefore, to use the orbital charts (Figures 1, 2, and 3) for any date other than December 31, 1957, requires that the charts be adjusted The following steps are used to update the locations of the planets on Figures, 2, and 3 for any date Step 1 Accurately determine the total amount of time (in days and in years) that has elapsed between December 3, 1957 (the date that the current figures represent) and the date you are seeking. (Note: One year equals 365.25 days.) Step 2 Advance each planet the number of days (for Mercury, Venus, and Mars) or years, including fractions (for Jupiter and Saturn), that have elapsed between December 31, 1957, and the new date. Mark the new position with a dot on the planet's orbit. Label the position with the new date. Step 3 For Earth, locate the date on the orbit that corresponds to the date you are seeking and mark the new position. (The time that has elapsed since the figures were drawn can be disregarded because in any year Earth will be located at the specified date in its orbit.) Step 4 Determine the position of the planet on the 360 reference circle by drawing a line from the Sun through the new position. To determine the constellation in which a planet is located, draw a line from the new position of Earth through the new position of the planet. Using the four steps for adjusting the planets' positions on the charts for any date, complete question 17 17. Determine the positions of the planets for tjku date: January 10, 2018. After calculating the number of days and years that have clapsed sinc the charts were drawn and entering your results below, complete Table 1 by listing the new location of each planet in degrees on the reference circle. Also, determine in which constellation the planet is located when viewed from Earth on the specified date and record your answer in Table 1 Note: You are given this answer.] (a) Date of new positions of the planets: January 10.2018 (b) Number of elapsed years since December 31, 1957- (c) Number of elapsed days since December 31, 1957 years [Round to 2 decimal places.] Table 1. Planet positions on today's date (or the date specified by your instructor). Use these dates: January 10, 2018 Sight from Sun Through Planet Sight from Earth Through Planet Read the footnotes! Planet Elapsed days/ Period Leftover x Planet PeriodLocation in Degrees In the Constellation Mercury Venus Earth orbits orbits orbits orbits orbits orbits days d) days (e) days (f) days (g) years) years (i) ars Jupiter Saturn Use orbital period of planet obtained from appendix table in textbook. If necessary, convert years to days using 365.25 days/year Round to 1 decimal place. For example, Mercury's period is 0.2409 y x 365.25 dly 87.9887 days, which rounds to 88.0 days. For Mercury, Venus, Earth, and Mars, give the number of orbits as a whole number plus a decimal to 2 places. For Jupiter, give the number of orbits as a whole number plus a decimal to 3 places. For Saturn, use 4 decimal places. The "leftover" will be the decimal portion of the number calculated in column 2. Multiply this decimal times the orbital period to get the number of days or years for column 3. Mark that spot on the planet's wheel and continue "To determine the constellation that Earth appears in, one has to look for the constellation that is behind the Earth on the specific date used (part a).
Explanation / Answer
a) 31 december 1957 to 31 december 2017 covers 60 years and 31 december 2017 to 10 january 2018 covers 10 days which means 10/365.25=.027 years, so total years are 60.027 years.
b) No. of elapsed days are=60*365.25+10
=21925 days
