2. The Orion Nebula is a gas-rich region in which stars are being born. The nebula is at a distance of about 1344 lyr from Earth. Suppose you observe a star in the Orion Nebula to have an apparent magnitude of 6.75. Calculate the absolute magnitude of the star. Also calculate the luminosity of the star in units of the solar luminosity (knowing that the absolute magnitude of the Sun is 4.8).
