- (The answer for 1 is not 0.000095 solar masses/year)F = 9/5 C + 32 ; C = 5/9 (F - 32); K = 273 + C; Lambda = 2900/T; T^4 = I (128)(10^8); I1/I2 = ( D2 / D1 )2 Show All Calculations What is the intensity of sunlight on planet XZEON if: The intensity of direct sunlight on earth is Ie = 2.0 calories per square centimeter per minute and Planet XZEON is 7.7 times farther from the sun than the earth is.If you were to send a beam of laser light to a space station above the atmosphere and just above the horizon, would you aim the laser above, below, or at the visible space station? Defend your answer.
- Infrared radiation from the center of our galaxy with a wavelength of about 2 μm (2 × 10-6 m) comes mainly from cool stars. Use this wavelength as Amax and find the temperature of the stars.What kind of object is the Messier Object M42, and where is it in the sky?If Jim could drive a Jetson's flying car at a constant speed of 330 km/hr across oceans and space, approximately how long (in millions of years, in 106 years) would he take to drive to a nearby star that is 8.7 light-years away? Use 9.461 × 1012 km/light-year and 8766 hours per year (365.25 days).
- How do you get the coordinates from here?Assuming it were possible, how long would it take a car traveling at 60 miles per hour to leave the solar system?Kepler’s First Law: Elliptical Planetary Orbits: The solar system major planet in the most elliptical solar orbit is little Mercury, which is the closest planet to the Sun. At Perihelion, Mercury’s distance from the Sun (Rp) is 0.31 AU. At Aphelion, Mercury’s distance from the Sun (Ra) is 0.47 AU. The intensity of Sunlight (I) that a planet receives from the Sun is inversely proportional to the square of that planet’s distance from the Sun (R). in other words, I = Constant / R2. Calculate how much more intense the Sunlight received by Mercury is at perihelion (p) than at aphelion (a): Rp2 = Ra2 = Ip / Ia = Ra2 / Rp2 =
- A planet was recently discovered orbiting the star Proxima Centauri, with an orbital radius of 0.05 AU. As seen from Earth, what is the maximum angular separation between this planet and Proxima Centauri, in arcseconds? The distance to Proxima Centauri is 4.24 light-years.Calculate how long radio communications from the spacecraft will take when it encounters Mars. The furthest distance from Earth to Mars is 2.66 AU. Remember that 1 AU = 1.5 x 1011 m and that light travels at 3 x 108 m/s. So how long will the radio messages take to travel this greatest distance of 2.66 AU? If two way communication between the Earth and the spacecraft involve a 1 s time lapse before an acknowledging signal is sent by the spacecraft, how long a time is there between sending a command to the spacecraft and receiving a reply?
