A star at a distance of 1 light year means that observer on earth would see the first light from the star after 1 . Explanation: 1 light year can be defined as the distance which light travels in one year in space. Whereas radial velocity searches look for planets in our immediate galactic neighborhood, up to 100 light years from Earth, and transit photometry can potentially detect planets at a distance of hundreds of light years from Earth, microlensing can find planets orbiting stars near the . The term light year is a measure of distance, so this star is 100 light years away, assuming it hasn't moved further away or gotten closer in the 100 years it … Wow.
