A. Use the data collected by Hubble space telescope and apply the Hubble's law.
B. Gather the data of angle of parallax from stellar observation after 6 months to get
its actual location.
C. Get the apparent brightness of the planet and calibrate its absolute magnitude
using the neighboring cepheids to know its actual distance.
D. Get the sum of all data using earth-baseline parallax, stellar parallax, variable and
cepheid stars to get its true brightness and provide an estimate of its distance.
