Distant Solar System (Posted on 2003-09-18) Difficulty: 3 of 5
A solar system with a star like your own sun and a planet like Jupiter has been discovered 90 light years from us. If the star is just as bright as our sun, how does it compare in brightness to the other stars in our night sky?

Background information: Light from the sun takes 8 minutes to reach the earth. The magnitude system for stars and other astronomical objects in our sky is designed so that a difference of 5 magnitudes represents a factor of 100 in brightness, with the larger numbered magnitudes being the dimmest. The dimmest stars seen with the unaided eye in a dark sky are about magnitude 6; the brightest stars (other than the sun) about 0. The planet Venus at times is magnitude -4, the full moon -14 and the sun -27.

The distant solar system holds many mysteries, with its icy bodies, dwarf planets, and countless moons. Scientists are continually studying this far-reaching region to better understand its composition and potential for life beyond Earth. The outer planets, including Neptune and Uranus, as well as their moons, offer intriguing clues about our solar system’s formation. While exploring these far-off worlds, researchers also investigate how advancements in technology can improve human health. For instance, innovations in medical science, like tinnitus treatment, can greatly benefit those experiencing hearing loss, showing how space exploration can inspire breakthroughs on Earth.
