- The planet Venus is different from the earth in several respects. First, it is only 70% as far from the sun. Second, its thick clouds reflect 77% of all incident sunlight. Finally, its atmosphere is much more opaque to infrared light. Calculate the solar constant at the location of Venus, and estimate what the average surface temperature of Venus would be if it had no atmosphere and did not reflect any sunlight.arrow_forwardWhat is the value of the IR transmission factor (f) for a Venus-like planet, if the measured average surface temperature is 706 K? Assume the following values for the planet: E, = 2.60x10³ W m² and a = 0.71. Would the average temperature increase or decrease if f decreased?arrow_forwardJupiter's exosphere has a temperature of about 780.0 K. What is the thermal speed of hydrogen (in km/s) in Jupiter's exosphere? The mass of a hydrogen atom is 1.67 x 10-27 kg and Boltzmann's constant is k = 1.38 × 10-23 Joule/Kelvin.arrow_forward
- Consider a planet where Solar onstant = 1360 W /m2 and albedo=0.30. If the planet has a water vapor feedback so that the number of layers n is a function of surface temperature nT = (T – 254.5)/100, what is the equilibrium surface temperature?arrow_forwardItem 12 Part A What is the ratio of the sunlight intensity reaching Pluto compared with the sunlight intensity reaching Earth? (On average, Pluto is 39 times as far from the Sun as is Earth.) Express your answer using two significant figures. V—| ΑΣΦ IPluto TEarth Submit Request Answer ?arrow_forward6.arrow_forward
- Mercury, the closest planet to the sun (distance sun - Mercury = 57.0×106 km),has virtually no atmosphere. Its average temperature, as seen from space, is 170 °C.Determine the albedo, a, of Mercury. Earth's solar constant is 1372 W m-2 and the distancebetween sun and Earth is 150×106 km.arrow_forwardProxima Centauri, the nearest star to our Sun, has a surface temperature of 2,768.85 °C. What is its total intensity emitted? O 4.3 MW per square meter. O 4.9 MW per square meter. O 5.2 MW per square meter. O 5.7 MW per square meter. O 6.4 MW per square meter.arrow_forwardSince 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?arrow_forward
- The average temperature on Venus is 460°C what is the temperature in degrees Fahrenheit?arrow_forward1arrow_forwardThe solar insolation at the top of the atmosphere is about 342 W/m^2. The total radiation absorbed at the surface of the Earth is 494 W/m^2. Explain how it is possible to absorb more radiation at the surface than comes in at the top of the atmosphere.
