Rogue Planet
A rogue planet is a celestial body with planetary mass that does not orbit a star but instead drifts freely through interstellar space.
TECHNICAL DEFINITION
A rogue planet, also known as an interstellar or free-floating planet, is a planetary-mass object that has been ejected from its star system or formed independently, lacking a gravitational bound to any star and traversing interstellar space.
BACKGROUND
Private spaceflight companies include non-governmental or privately owned entities focused on developing and/or offering equipment and services geared towards spaceflight, both robotic and human. This list includes both inactive and active entities.

USAGE NOTE
Detecting rogue planets is challenging but offers insights into planetary formation and ejection mechanisms.
DEVELOPERS
Organizations developing technology related to Rogue Planet.
The United States' space agency is developing the Nancy Grace Roman Space Telescope, a flagship observatory whose prime objectives include a large-scale gravitational microlensing survey specifically designed to find thousands of exoplanets, including a significant population of rogue planets.
A long-term astronomical survey project led by the University of Warsaw, Poland. Using a dedicated telescope in Chile, OGLE is one of the world's leading projects in detecting rogue planet candidates by continuously monitoring millions of stars for gravitational microlensing events.
An international organization whose Euclid space telescope, while primarily designed to map the dark universe, will survey a vast area of the sky. This survey data is expected to reveal a large number of microlensing events, providing a significant opportunity for the discovery of free-floating planets.
Operated by the Korea Astronomy and Space Science Institute (KASI), KMTNet is a system of three identical wide-field telescopes in Chile, South Africa, and Australia. This global network provides 24-hour continuous observation to detect and characterize microlensing events, making it a key instrument in the search for rogue planets.
The JWST, a space-based infrared observatory led by NASA in partnership with ESA and CSA, has the sensitivity to directly image young, massive rogue planets that are still warm from their formation. It has already successfully identified unbound Jupiter-mass binary objects (JuMBOs).
A next-generation astronomical observatory under construction in Chile that will conduct the Legacy Survey of Space and Time (LSST). Its deep, wide, and rapid survey of the sky will be a powerful tool for discovering transient events, including a very large number of gravitational microlensing signatures from rogue planets.
A collaborative project between researchers in Japan and New Zealand using the Mt. John University Observatory. The MOA group is a long-standing leader in searching for gravitational microlensing events to find exoplanets and has been instrumental in identifying rogue planet candidates.
