HD 33283 b is an exoplanet orbiting around HD 33283

HD 33283

HD 33283 is an 8th magnitude star in the constellation Lepus. It is located 86.88 parsecs 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 mass

Mass

Mass can be defined as a quantitive measure of the resistance an object has to change in its velocity.In physics, mass commonly refers to any of the following three properties of matter, which have been shown experimentally to be equivalent:...

 of the planet is about ¹/₃ that of Jupiter

Jupiter

Jupiter is the fifth planet from the Sun and the largest planet within the Solar System. It is a gas giant with mass one-thousandth that of the Sun but is two and a half times the mass of all the other planets in our Solar System combined. Jupiter is classified as a gas giant along with Saturn,...

 or about the same as Saturn

Saturn

Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Saturn is named after the Roman god Saturn, equated to the Greek Cronus , the Babylonian Ninurta and the Hindu Shani. Saturn's astronomical symbol represents the Roman god's sickle.Saturn,...

. However, the planet orbits very close to the star

Star

A star is a massive, luminous sphere of plasma held together by gravity. At the end of its lifetime, a star can also contain a proportion of degenerate matter. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth...

, taking only 18 days to complete its orbit with average speed

Orbital speed

The orbital speed of a body, generally a planet, a natural satellite, an artificial satellite, or a multiple star, is the speed at which it orbits around the barycenter of a system, usually around a more massive body...

of 86.5 km/s. Despite of this, its orbit is eccentric, bringing it as close as 0.075 AU to the star and as far away as 0.215 AU.
