In our solar system, everything seems to be in order: The smaller rocky planets, such as Venus, Earth or Mars, orbit relatively close to our star. The large gas and ice giants, such as Jupiter, Saturn ...
Across the galaxy, astronomers now see that planetary systems fall into four broad classes, and our own solar system, part of the rare Ordered group, is only one of them. At the same time, discoveries ...
Astronomers have classified planetary systems into four distinct categories, based on the sizes and arrangements of their planets. As it turns out, the architecture of our own solar system is the ...
Washington DC — New theoretical work shows that gas-giant planet formation can occur around binary stars in much the same way that it occurs around single stars like the Sun. The work is presented ...
A rocky exoplanet in the LHS 1903 system defies planet formation models, hinting that gravitational upheaval reshaped the red dwarf’s four worlds.

Astronomers have discovered a unique planetary system where planets are arranged inside out
The fourth planet in the system is a rocky world, while the second and third ones are gas planets.
Forty light-years away, seven Earth-sized planets orbit around a dim red dwarf star in one of the most tightly packed planetary systems ever discovered. The TRAPPIST-1 system has captivated ...
White dwarfs, the compact remnants of low- to intermediate-mass stars, offer a unique window into the fate of planetary systems. Recent observational and theoretical work has revealed that many white ...
Artist impression of the four classes of planetary system architecture. A new architecture framework allows researchers to study an entire planetary system at the systems level. If the small planets ...
NASA’s Kepler Mission, launched in 2009, revolutionized the field of exoplanet science. It provided a vast amount of information about planets orbiting stars other than the Sun and the planetary ...
Astronomers have long been aware that planetary systems are not necessarily structured like our solar system. Researchers have now shown that there are in fact four types of planetary systems. In our ...
