A study of comet motions suggests that there is a second alignment plane in the solar system. Analytical investigations of long-term comets’ orbitals show that the comet’s aphelia, the point where they are farthest from the Sun, comes close to the well-known elliptical plane where the planets reside or a new find “empty “The Revolution. “It has important implications for the model of how a comet originally formed in the solar system.


In the solar system, planets and most other bodies run in approximately the same orbital plane, known as the elliptical, but there are exceptions such as comets. Comets, especially long-period comets, which take tens-thousands of years to complete each orbit, are not limited to the area near the eclipse; They are seen moving in different directions.

Models of the formation of the solar system suggest that long-term comets were originally formed near the elliptical and later scattered into orbit, orbiting today through gravitational differences, especially with gas giant planets. But even with the scattering of planets, the comet’s indifference, the point where it is farthest from the Sun, must remain near the eclipse. Other external forces are needed to explain the observed distribution.

The solar system does not exist in isolation; The gravitational field of the Milky Way galaxy in which the solar system also resides has a small but non-negligible effect. Erica Higuchi, an assistant professor at the University of Occupational and Environmental Health in Japan and a member of the first NAOJ RISE project, studied the effects of galactic gravity on long-term comets through analytical investigation of equations of orbital motion.

He showed that when galactic gravity is taken into account, a long-period comet’s aphelia gathers about two planes. The first well-known Ecliptic, but also a second “Empty Ecliptic.” Ecliptic inclination is about 60 degrees with respect to the disk of the Milky Way. The empty ecliptic is also tilted by 60 degrees, but in the opposite direction. Higuchi calls it an “empty eclipse” based on mathematical nomenclature and because it initially contains no objects, only later is populated with scattered comets.

Higuchi confirmed his predictions by cross-checking with numerical computations performed in part in the PC cluster of the Computational Astrophysics Center of NAOJ. Comparison of the analytical and computational results of the long-term comet data listed in NASA’s JPL Small Body Database shows that the distribution has two peaks, as ecliptic and near empty ecliptic as predicted. This is a strong indication that formation models are correct and ellipses are formed on comets. However, Higuchi warns, “Sharp peaks do not occur exactly on elliptical or empty elliptical planes, but rather near them. Investigating the distribution of small objects observed involves several factors. The distribution of long-term comets There will be a detailed investigation. Our future work. The All-Sky Survey Project, known as the Legacy Survey of Space and Time (LSST), will provide valuable information for this study. ”
