A comet that was seen in April 574 by Chinese astronomers on a day known by them as the Woo Woo day was spotted again in May 1994. Assume the time between observations is the period of the Woo Woo day comet and its eccentricity is 0.9932.What are (a) the semimajor axis of the comet’s orbit and (b) its greatest distance from the Sun in terms of the mean orbital radius RP of Pluto?
In the Tsiolkovsky's equation, the parameter “delta v”, could I use “delta v”as “v” in the equation v=sqrt(GM/r) or are they different. For example if a satellite is in a geosynchronous orbit with a “delta v” of 2km/s, could I use the 2km/s to calculate the radius of orbit? Thanks
Suppose that a comet travels this path and is 400 astronomical units from the sun asits closest, find the hyperbola equation of the path of the comet if the sun is 1000 astronomical unitsfrom the center of the path. (Assume that the center is at the origin.)
Suppose a comet were discovered approaching the Sun, one whose orbit would cause it to collide with Earth 20 months later, after perihelion passage. (This is approximately the situation described in the science-fiction novel Lucifer’s Hammer by Larry Niven and Jerry Pournelle.) What could we do? Would there be any way to protect ourselves from a catastrophe?
A comet has a period of 76.3 years and moves in an elliptical orbit in which its perihelion (Closest approach to the Sun) is 0.610 AU. Find (a) the semimajor axis of the comet and (b) an estimate of the comets maximum distance from the Sun, both in astronomical units.

Check Your Understanding The nearly circular orbit of Saturn has an average radius of about 9.5 AU and has a period of 30 years, whereas Uranus averages about 19 AU and has a period of 84 years. Is this consistent with our results for Halley’s comet?
The perihelion of the comet Legerkvist is 2.61 AU and it has a period of 7.36 years. Show that the aphelion for this comet is 4.95 AU.
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…
Let's define the gravitational pull between Earth and the Sun as 1 Earth-pull. What is the pull that Jupiter has on the Sun in Earth-pulls? Jupiter has a mass of 318 Earth masses. Jupiter is located at 5.20 AU from the Sun.
The mass of the Sun is approximately 333,000 times that of the Earth, and the mass of the Earth is 6 * 1024 kg. The Earth orbits the Sun in (approximately) a circle of radius 150 million km. Let's say an asteroid of mass 1000 kg happens to be orbiting the Sun in a circle of the same radius as the Earth, but the orbit is tilted relative to that of the Earth The distance between the asteroid and the Earth could be large (a) or small (b). When the asteroid gets too close to the Earth, it will be deflected by Earth's gravity. (a) If the asteroid feels only the gravitational force of the Sun, then this force is ______ Newton (pick the closest answer). (b) If the asteroid is at a distance of 250,000 km from the Earth, the force it feels from the Earth is _____ Newtons (pick the closest answer). All distances above are measured between the centers of mass.
