AVHRR/3 is a multispectral sensor onboard NOAA-15, a sun- synchronous platform that has an orbital period of 102.12 min. It has a swath width of 2900 km. How many AVHRR/3 orbits are produced per day? Do 2 consecutive orbits overlap at the equator? Explain your answer. (Hint: Assume Earth’s circumference at the equator = 40000 km)

1. Consider our Sun - it is in orbit around the center of our Milky Way Galaxy. The velocity of the Sun in its orbit is about 250 km/s. The distance to the center of the galaxy is about 9.1 kpc (kiloparsecs). We can use Kepler's third law to calculate the mass of the galaxy interior to the Sun's orbit. We assume that the orbit is circular so that the semimajor axis is just the radius of the circular orbit = 9.1 kpc. First we need to calculate the number of AU's in 9.1 kpc. (Note that 1 Крс - 1000 рс - 3260 1t yrs and 1 pc - 206,265 AU.) %3D a =r =9.1kpc = (9.1kpc) 1000 pc 206,265AU] 1kpc AU Sun 1pc

In Table 2, there is a list of 15 planets, some of which are real objects discovered by the Kepler space telescope, and some are hypothetical planets. For each one, you are provided the temperature of the star that each planet orbits in degrees Kelvin (K), the distance that each planet orbits from their star in astronomical units (AUs) and the size or radius of each planet in Earth radii (RE). Since we are concerned with finding Earth-like planets, we will assume that the composition of these planets are similar to Earth's, so we will not directly look at their masses, rather their sizes (radii) along with the other characteristics. Determine which of these 15 planets meets our criteria of a planet that could possibly support Earth-like life. Use the Habitable Planet Classification Flow Chart (below) to complete Table 2. Whenever the individual value you are looking at falls within the range of values specified on the flow chart, mark the cell to the right of the value with a Y for…

(a) The distance to a star is approximately 7.80 1018 m. If this star were to burn out today, in how many years would we see it disappear? years (b) How long does it take for sunlight to reach Saturn?

I have submitted this question 4 times and the responses have all been wrong. Please put your best person on this. I have tried 19.9923, 20.6, and 20.69 for part 1 and those are all wrong and I have tried 14.1122, 14.80, 8.41781, and 14.87 for part 2 and those are all wrong too. Please help! I'm wasting questions!
