What is psr j1719 1438b?

PSR J1719-1438b is an exoplanet that orbits around a pulsar star named PSR J1719-1438, located approximately 4,000 light-years away from Earth. The exoplanet was first discovered in 2011 using the Arecibo Observatory in Puerto Rico.

PSR J1719-1438b is a dense, rocky world that is believed to have a mass similar to that of Jupiter but is much smaller in size, approximately five times larger than the Earth. The exoplanet orbits its host star every two hours and 10 minutes, which is faster than any other known exoplanet.

What's unique about PSR J1719-1438b is that it orbits very close to its pulsar star, at a distance of only 600,000 km, which is about 95% of the distance from the Earth to the Moon. Its close proximity to the host star means that its surface temperature is estimated to be around 10,000 degrees Celsius, making it hotter than the surface temperature of some stars.

PSR J1719-1438b is also known for its high carbon-to-oxygen ratio, which indicates that it is likely composed of diamond, instead of rock or gas. In fact, it is estimated that the exoplanet could contain approximately 10 billion trillion trillion carats of diamond, although it is unlikely that this could ever be harvested due to the extreme conditions of its environment.

Overall, PSR J1719-1438b is a fascinating exoplanet that provides valuable insights into the diversity of exoplanets and the extreme conditions that some can exist in.
