Answer:
It is larger than the second star.
It is younger than the second star.
Explanation:
The star's actual brightness depends on two factors: size and surface temperature. If we take two stars of the same size, hotter star would look brighter. If we take two stars with the same surface temperature, bigger star would like brighter.
In the given scenario, two options can be correct. The first star might be larger than the second one or it can be younger as younger stars are hotter.
