An asteroid has a perihelion distance of 2.0 AU and an aphelion distance of 4.0 AU. Calculate its orbital semimajor axis, eccentricity, and period
Foundations of Astrophysics, 1st Edition (PLEASE EXPLAIN YOUR WORK) 11.7: Comet Halley has a perihelion distance q = .587 AU and orbital eccentricity e = .967. a) What is the semimajor axis of its orbit? b) What is its orbital speed at perihelion? c) What is its aphelion distance? d) What is its orbital speed at aphelion?
Halley’s Comet has a perihelion distance of 0.6 AU and an orbital period of 76 years. What is its aphelion distance from the Sun
6. Given that the distance to the Moon is 384000 km, and taking the Moon’s orbit around Earth to be circular, estimate the speed (in kilometers per second) at which the Moon orbits the Earth. 7. The baseline in Figure 0.19 in the textbook is 100 m and the angle at B is 60 degrees. Using the tangent function, calculate the distance from A to the tree Ch. 1 Discussion Questions 2. The benefit of our current knowledge lets us...
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?
Duende has an elliptical orbit about the Sun, with a perihelion distance of 0.829 AU and aphelion distance of 0.992 AU. What is the period of its orbit (in years)?
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
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. ...
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
A comet in orbit around the sun has an orbital eccentricity 0.4 and semi-major axis 6 AU. What is the comet's furthest distance from the Sun in AU?
