- Find the distance in parsecs to Proxima Centauri, which has an annual parallax of 0.772 arcsec.31) Star Sirius has an apparent magnitude of -1.47 and an absolute magnitude of 1.41. Estimate the distance to Sirius.The right ascension and declination of the seven stars of the Big Dipper are given below: Star Right Ascension Declination Alkaid 13h48m +49° 19' Mizar 13h24m +54°56' Alioth 12h54m +55°58' 12h15m +57°02' 11h54m +53°42' Merak 11h02m +56°23' Dubhe 11h04m +61°45' (1) For what range of latitude are all the stars of the Big Dipper circumpolar? Megrez Phecda
- What is a variable magnitude?I am trying to plot the ground tracks of an orbit. But I am having a problem with finding the longitude. The equation for the longitude is shown in the image. Is the Theta GMST initially zero because the greenwich meridian points to the Aries point (x-axis). How do you calculate alpha or vernal equinox? I saw a formula for alpha which is alpha = arctan(ry/rx), but the formula was for Right Ascension angle. Is the right ascension angle the same as vernal equinox. If not, then what is the formula for vernal equinox.What would the angle between the Sun and the Earth be if the solar system were viewed from a distance of 1 pc?
- Is wanting one answer which is to calculate the magnitude A-2B12 Suppose that you measure the parallax angle for a particular star to be 0.5 arcsecond. The distance to this star is A) 2 parsecs. B C 0.5 parsec. E 5 light-years. (D) 5 parsecs. 0.5 light-year.At the distance of Earth, 1AU, the Sun's apparent brightness in the sky is about 1250 W/m 2 . What is the brightness that we would measure from a distance of 0.5 AU? What is the brightness that we would measure from a distance of 2.0 AU?
