A comet has a period of 72.3 years and moves in an elliptical orbit in which its perihelion (closest approach to the Sun) is 0.650 AU. Find the semimajor axis of the comet and an estimate of the comet's maximum distance from the Sun, both in astronomical units. (a.) the semimajor axis of the comet (in AU). (b.) an estimate of the comet's maximum distance (in AU) from the Sun.
QUESTION 1: The International Space Station has a mass of 4.19 ✕ 105 kg and orbits at a radius of 6.79 ✕ 106 m from the center of Earth. Find the gravitational force exerted by Earth on the space station, the space station's gravitational potential energy, and the weight of a 92.3 kgastronaut living inside the station. HINT (a) the gravitational force (in N) exerted by Earth on the space station (Enter the magnitude.) N (b) the space station's gravitational...
A comet moves about the Sun in an elliptical orbit, with its closest approach to the Sun being about 0.620 AU and its greatest distance from the sun being 35.5 AU (1 AU = the Earth-Sun distance). If the comet's speed at closest approach is 54.0 km/s, what is its speed when it is farthest from the Sun? (The gravitational force exerted by the Sun on the comet is parallel to the moment arm, so exerts no torque. Therefore, angular...
If a comet has a perihelion of 1.2 AU and an aphelion of 4.9 AU, what is the semi-major axis of the comet's orbit? Express the answer using two significant figures. axis: AU What is the period of the comet's orbit around the Sun? period: years
If a comet has a perihelion of 0.80 AU and an aphelion of 9.1 AU, what is the semi-major axis of the comet's orbit? Express the answer using two significant figures. axis: What is the period of the comet's orbit around the Sun? period: years
(1) Halley's Comet and Kepler's Laws: Halley's Comet orbits the Sun every 76.0 years. Its elliptical orbit has an eccentricity of 0.97. Using that information and the Kepler material in Math Insight Box 3.2 (p.70) and Figures 3.16, 3.17 and 3.18: 40 points total] (a) Find the comet's average distance from the Sun (semimajor axis, a) (b) Find its closest and furthest distances from the Sun: the Perihelion & Aphelion distances.
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?
1. Halley’s Comet moves in an elongated elliptical orbit around the Sun. Its distances from the sun at perihelion and aphelion are 8.75 × 107 km and 5.26 × 109 km, respectively. Find the orbital semi-major axis, eccentricity, and period for Halley’s Comet. 2。 A toboggan loaded with students (total weight 300 kg) slides down a snow-covered slope. The hill slopes at a constant angle 40.0 ◦ , and the toboggan is so well waxed that there is virtually no...
A comet orbits the Sun with a period of 67.41 years. The comet’s distance of closest approach to the Sun (perihelion) is 1.239 AU. What is the maximum distance of the comet from the Sun (aphelion)? Give your answer in AU.
Pluto's orbit around the Sun is highly elliptical compared to the planets in our Solar System. It has a perihelion distance of 29.7 AU and an aphelion distance of 49.5 AU. a) What is the semi-major axis of Pluto's orbit, in AU? b) What is Pluto's orbital period, in Earth years?
