in the constellation
Lepus
. It is located 86.88 parsec
s (283.37 light years) away from the solar system
. HD 33283 is similar to our Sun
in terms of spectral type [G4V]. However, the star dwarfs the Sun by 24% more massive, 20% larger, 217 K hotter, and 232% more metals. The star is younger than our Sun by 40%.
In 2006, Johnson found a jovian planet orbiting HD 33283.

Solar System
The Solar System consists of the Sun and the astronomical objects gravitationally bound in orbit around it, all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago. The vast majority of the system's mass is in the Sun...
