The distance between the sun and Earth is 1.00 au (astronomical unit) and the energy flux from the sun is 1372 W m-2 at this distance. The distance between the sun and Mars is 1.51 au. Mars has an albedo of 0.149. Determine the effective temperature (in K) of Mars, as seen from space.

An astronomical unit (AU) is equal to the average distance from Earth to the Sun, about 92.9 × 106 mi. A parsec (pc) is the distance at which a length of 1 AU would subtend an angle of exactly 1 second of arc (the figure). A light-year (ly) is the distance that light, traveling through a vacuum with a speed of 186000 mi/s, would cover in 1.0 year. Express the Earth–Sun distance in (a) parsecs and (b) light-years.

A light-year is the distance light travels in one year (atspeed=2.998×10^8m/s). An astronomical unit (AU) is the average distance from the Sun to Earth, 1.50×10^8km. How many AU are there in 4.00 light-year?

The heliopause is now estimated to be something around 100 AU (1 AU = Astronomical unit = about the earth sun distance). See the wikipedia article: http://en.wikipedia.org/wiki/Heliosphere From reading a book on NASA's Voyager mission, I learned that before the launch of these spacecraft, the expectation was that the heliopause was at around Jupiter or Saturn's orbit which is about 5 to 10 AU. The book says that as the spacecraft continued to move away from the sun, the space...

A comet of mass 1.20 ✕ 1010 kg moves in an elliptical orbit around the Sun. Its distance from the Sun ranges between 0.200 AU and 62.0 AU. (Note: 1 AU = one astronomical unit = the average distance from the Sun to Earth = 1.496 ✕ 1011 m.) (a) What is the eccentricity of its orbit? (b) What is its period? ______yr (c) At aphelion what is the potential energy of the comet-Sun system? _____J

Assuming the Sun radiates as a blackbody at a temperature of 5800 K, calculate the expected surface temperature of the Earth, assuming that the Earth also acts as a perfect blackbody. Assume the Earth absorbs an amount of energy proportional to its cross-sectional area, but radiates as a spherical blackbody. If the Earth is in thermal equilibrium with outer space, then the energy received (mostly at visible wavelengths) must equal the amount of energy re- radiated (mostly) in the infrared....

Dave is sitting on a spaceship orbiting the Earth (1 au from the sun). At this distance, his solar panels gather an intensity of 1000 (watts/m^2) from the Sun's radiation. Dave wants to gather enough energy to run his coffee machine which needs an intensity of 20 (watts/m^2) Question 1: Dave flies to Saturn (which is approximately 10 au from the sun) and at somewhere along the way his coffee machine no longer gets enough power. What intensity do his...

The energy received by the Sun, or irradiance (W/m2) is affected by our distance from the Sun and interactions with Earth’s atmosphere. For each of the following locations, describe the expected irradiance value in W/m2.

What should be the temperature on a spherical asteroid located between Mars and Jupiter, twice as far from the Sun as Earth? The asteroid has no atmosphere, and its albedo is 0.15. Hint: Because sunlight intensity falls as the inverse square of the distance, the solar constant at Venus is a factor of (150/108)² larger than at Earth
