description PSR 1257+12 c Overview
PSR 1257+12 c is a rocky exoplanet orbiting the pulsar PSR B1257+12. Its discovery in 1992 alongside other planets around this rapidly rotating neutron star represents the first confirmed system of its kind. This planet, classified as a super-Earth, is particularly notable for providing valuable data through pulsar-timing variations. Astronomers and researchers studying planetary formation, stellar evolution, and gravitational interactions find it a significant subject of investigation.
help PSR 1257+12 c FAQ
What type of star does PSR 1257+12 c orbit?
PSR 1257+12 c orbits a pulsar named Lich, which is the collapsed, rapidly spinning core of a dead massive star. It is incredibly rare for planets to exist in a pulsar system due to the violent nature of supernova explosions.
Who discovered PSR 1257+12 c?
The planet was co-discovered in 1992 by astronomers Aleksander Wolszczan and Dale Frail. They detected the planets by measuring precise timing variations in the radio pulses coming from the host pulsar.
What is the nickname of PSR 1257+12 c?
PSR 1257+12 c is informally known as Poltergeist. The planets in this system were given ghostly nicknames because they orbit a "dead" star and were the very first exoplanets ever confirmed by scientists.
How large is the exoplanet PSR 1257+12 c?
PSR 1257+12 c is classified as a super-Earth. It has a mass estimated to be over four times that of Earth, making it significantly heavier than any planet in our Solar System's inner region.
