An astronomer is studying two stars of identical radii. The peak wavelength of the spectrum of the first star is observed at 600 nm, and the peak wavelength spectrum of the second star is at 400 nm. Given that both stars seem equally bright from Earth, use Wien's law and the Stefan-Boltzmann equation to deduce which star is farther from Earth.

• A. The star, peaking at 400 nm, is farther from Earth.
• B. The star, peaking at 600 nm, is farther from Earth.
• C. Both stars are at an equal distance from the Earth.
• D. The information is insufficient to decide which star is closer to Earth.
