Comet P/1999 R1 has a perihelion of 0.0570 AU and aphelion of 4.99 AU. Using the results of the previous problem, find its speed at aphelion. (Hint: The expression is for the perihelion. Use symmetry ot rewrite the expression for aphelion.)
Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?
Find the Hohmann transfer velocities, vEllipseEarth and vEllipseMars ,needed for a trip to Mars. Use Equation 13.7 to find the circular orbital velocities for Earth and Mars. Using Equation 13.4 and the total energy of the ellips (with semi-major asix a), given by E=GmMs2a , find the velocities at Earth (perihelion) and at Mars (aphelion) required to be on the transfer ellipse. The difference, v , at each point is the velocity boost or transfer velocity needed.

An object of mass mm is launched from a planet of mass MM and radius RR. a) Derive and enter an expression for the minimum launch speed needed for the object to escape gravity, i.e. to be able to just reach r=∞. b) Calculate this minimum launch speed (called the escape speed), in meters per second, for a planet of mass M=2.73×1023kg and R=86.2×103km.
The orbital period of the Earth and Mars are Pg = 365.26 d and P respectively. Assuming circular orbits, the synodic period P, for two planets to be at the same angular position from the Sun can be found using the equation 1 = 686.97 d, %3D Pe Pe a) The last opposition of Mars occurred on 13 Oct 2020. Using the information above, calculate the interval between two consecutive Martian oppositions, and estimate the date of its next opposition. b) It is said that Mars at oppositions near its perihelion occur roughly once every 15 years, with the last event occurring on 27 Jul 2018. Using the synodie period derived, find a more accurate interval, and estimate the date for the next time this event occurs. c) The actual dates for the next Martian opposition and opposition at perihelion are 8 Dec 2022 and 15 Sep 2035, respectively. State two reasons why your estimations may have differed from these dates. In stage 10 of the evolution of a Sun-like star, helium fusion occurs. Write down the…
A sateltle orbits at a height of 6,000 km above the earth's surface. REarth = 6.38 x 10° m, mEarth = 5.98 x 1024 kg. What is this satelite's speed, in km/s (kilometer per second)? Use G = 6.67 x 10-11 N-m2/kg2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. A Moving to another question will save this response.
An asteroid closely passes the Earth at a range of 17200mi and a relative speed of 7.8km/s.The diameter is estimated at 30mwith a specific gravity of 3. If this asteroid had impacted Earth, how much energy would have been released? Express this quantity in units of mega-tons (M ton) where a megaton is the energy released by one million metric tons of TNT explosive. A metric ton is 1000kgand the explosive energy density of TNT is 4184J/g.Hint: If the asteroid hits the Earth, its relative velocity becomes zero. Ignore any change in asteroid velocity due to gravitational acceleration or air resistance.
(a) A reasonably accurate value for the AU is 1.50 × 101 m. If the year is a × 107 s, (2) (a good approximation, and one easy to remember) calculate Earth's speed in km/s assuming a circular orbit about the Sun. (b) The experimental determination (first attempted by Cavendish in 1797/98) yields G = 6.67×10-11 N-m²/kg?. Calculate the mass of the Sun. (c) On the other hand, when we measure distances in AU and speeds in km/s, the constant in the Vis-Viva Equation is GM = 900. Explain why this is the case. (d) Once we know the distance to the Sun, using its angular size one could determine that the radius of the Sun is approximately Rsun = 7 × 10* m. Calculate the ratio of the Sun's density to that of water.
