Exoplanets in eccentric orbits experience large temperature swings during their orbits. Suppose you had to plan for a mission to such a planet. Based on Kepler’s second law, does the planet spend more time closer or farther from the star? Explain.
In 1993 the Galileo spacecraft sent home an image of asteroid "243 Ida" and a tiny moon "Dactyl" orbiting the asteroid. Assume that the small moon orbits in a circle with a radius of r = 100 km from the center of the asteroid with an orbital period of T = 27 hours. a. Show and explain how we derived Kepler's 3rd law using Newton's 2nd Law, the definition for centripetal acceleration, and the equation for gravitational force. b. Use your result for Kepler's 3rd Law to determine the mass of the asteroid. c. If the asteroid has a radius of about 16 km calculate the approximate value for the acceleration due to gravity, g, on its surface. d. What velocity would you need to achieve in order to lift off and leave this asteroid? e. Use Newton's 2nd Law, the definition for centripetal acceleration, and the equation for gravitational force to determine an expression for circular orbital velocity. f. What is the orbital velocity of the small moon if we assume it is in a circular orbit?
New Horizons was launched by NASA lastJanuary 19, 2006 to a mission to the dwarfplanet Pluto. On July 15, 2015, it flew 12,500km above the surface of Pluto, making it thefirst successful spacecraft to explore the dwarfplanet. Explain how the gravity of Jupiterhelped New Horizons to propel faster to Pluto.
The gravity on Mars is about 38% that of Earth's gravity. Let's say some cargo has a mass of 15 kg here on Earth. First, what would be the weight of that cargo in kilograms on Mars? Explain your answer. Second, what would be the mass of that cargo in kilograms on Mars? Explain your answer.

In the solar system, there are many small pieces of rocks (i.e., asteroids) floating around that we canactually detect and whose orbits we can track. We’ll learn more about these later, but for now let’stake a look at the orbits of the asteroids. You’ll want to keep 3-4 significant digits throughout this problemand report all periods in years.(a) Imagine here is a gap in semi-major axis near a hypothetical 2.502 AU. What would the orbital period be of asteroids at this location?(b) The explanation for the missing asteroids has to do with gravitational interactions from themassive planet Jupiter located at 5.204 AU. Calculate is the orbital period of Jupiter in years? This is ungraded problem that uses Kepler's 3rd law.
What fractional decrease in flux, δF/F, would be caused by an Earth-like planet transiting a Sun-like star? If a transit of the Earth across the Sun were viewed by a very distant observer in the Earth’s orbital plane, how long would the transit last?[Hint:You will need the orbital velocity of the Earth,vorb= 30km s−1.]

asap do all steps please An asteroid in our Solar System has an eccentricity of 0.550 and a perihelion (closest to Sun) distance of 0.800 AU (Astronomical Units). a)What is its semimajor axis in AU? b)What is its orbital period in Earth years? (Hint: use the simpler form of Kepler’s law for orbitsaround our Sun. You do not need to know 1AU in m). c)What is the ratio of its maximum to minimum speedduring its orbit, vmax/vmin (3 sig figs)? (Hint: use a conservation law) d)Choose one: The asteroid’s total mechanical energy is: i) positive, ii) zero iii) negative, iv) any of theaboveare possible. e) The Earth’s orbit is very close to circular and draw it as acircle of radius 1AU (OK to trace sometime at least the size of a quarter or draw by hand). Label an “S” where the Sunis. Carefully mark theperihelion of the asteroid to the left of the Sun with a “P” and aphelion with an “A” to the right of the Sunto scale (use your ruler to measure it). Show the extent of the asteroid’s semimajor…
Mission to Titan: NASA is considering sending a 600 kg space probe into orbit around Titan in order to map its surface. This would be followed a few years later by a 320 kg robotic lander that would land on the surface of Titan in order to look for life. a) What would be the space probe’s velocity and orbital period if the probe were to orbit at an altitude of 70 km above the surface of Titan? b) What force would the lander’s thrusters need to produce in order to allow the lander to hover just above the surface of Titan?
Measure the periods for each planet. Measure the orbital radius of each planet. Calculate the ratios of square of the periods and cubed of the radii for the planets. Compare the results and comment if your result confirms Kepler's Third Law. (Pic1 has the yellow and bluw planets points plotted. Pic2 has the grey and red planet plots listed.)
I'm still confused--what is T? What is a? What is the satellite's orbital period?
