HD 23596 b
Encyclopedia
HD 23596 b is an exoplanet approximately 170 light years away in the constellation
Perseus
. The planet is very massive, at least 7.8 times that of Jupiter
, classifying as mid-superjovian. Based on its mass, the planet would probably be a gas giant
with no solid surface. The planet orbits at the average distance of 2.83 AU, taking 1565 days to complete its orbit with average velocity of 19.7 km/s. The eccentricity of the planet’s orbit is higher than all the planets in our solar system
, bringing as close as 2.00 AU to as far as 3.66 AU from the parent star.
The planet was discovered by Perrier et al. in 2002 using his radial velocity technique to look for changes in inward (blue-shifting) and outward (red-shifting) radial stellar motion in the sky.
Constellation
In modern astronomy, a constellation is an internationally defined area of the celestial sphere. These areas are grouped around asterisms, patterns formed by prominent stars within apparent proximity to one another on Earth's night sky....
Perseus
Perseus (constellation)
Perseus is a constellation in the northern sky, named after the Greek hero Perseus. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations defined by the International Astronomical Union...

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,...

Gas giant
A gas giant is a large planet that is not primarily composed of rock or other solid matter. There are four gas giants in the Solar System: Jupiter, Saturn, Uranus, and Neptune...

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...
