Earth and Mars are 1.0 AU and 1.52 AU away from the Sun, respectively. Given that the period of Earth's orbit around the Sun is 1 yr, calculate the period of the orbit of Mars around the Sun. (1 AU = 150 × 106 km)
a. 0.28 yr
b. 1.9 yr
c. 0.53 yr
Homework Answers
R1= 1 AU and R2 =1.52 AU
T1 = 1 yr and T2 = ?
We know that , (T1^2)/(R1^3) = (T2^2)/(R2^3)
(1^2)/(1^3) =(T2^2)/(1.52^3)
1*3.512 = T2^2
T2 = 1.874 AU
Approximately , T2 = 1.9 AU

The semimajor axis of Mars orbit is about 1.52 astronomical units (au), where an au is the Earth's average distance from the Sun, meaning the semimajor axis of Earth's orbit is 1 au. To go from Earth to Mars and use the least energy from rocket fuel, th
The semimajor axis of Mars orbit is about 1.52 astronomical units (au), where an au is the Earth's average distance from the Sun, meaning the semimajor axis of Earth's orbit is 1 au. To go from Earth to Mars and use the least energy from rocket fuel, the orbit has a semimajor axis of 1.26 au and an eccentricity of about 0.21. Starting at Earth's orbit, to follow this path we give the spacecraft an orbital velocity of 40 km/s. ...

On Jan. 2 this year, Earth was 1.471x10^13 cm from the Sun, its closest point to the Sun. The semi-major axis of Earth's orbit around the Sun is 1AU (1.496x10^13 cm. Use this information to determine: A. The eccentricity of Earth's orbit around the Sun. B. The difference between the maximum distance between the Earth and Sun, and the minimum distance between the Earth and the Sun. Convert your answer to AU

The orbit of a 1.5 ✕ 1010 kg comet around the Sun is elliptical, with an aphelion distance of 33.0 AU and perihelion distance of 0.850 AU. (Note: 1 AU = one astronomical unit = the average distance from the Sun to the Earth = 1.496 ✕ 1011 m.) (a)What is its orbital eccentricity? (b)What is its period? (Enter your answer in yr.) (c)At aphelion what is the potential energy (in J) of the comet—Sun system?
