Sentences with word «semimajor»

Interestingly, the most distant [TNOs], with semimajor axes greater than 150 AU and perihelia beyond Neptune, also seem to have values for such angles comparable to those of Sedna and 2012 VP113.

Because of that, the Earth's orbital semimajor axis must slowly increase.

The semimajor axis of the planet is closer relative to that of its hierarchical triple - star system than for any known exoplanet within a stellar binary or triple, making HD 131399 dynamically unlike any other known system.

Modelling simulations by Wilner's team (including Matt Holman, Paul Ho, and Marc Kuchner) suggested that the semimajor axis of the planet's orbit may center around 30 AUs — at Neptune's orbital distance in the Solar System.

In addition, «it was decided that, for naming purposes, any Solar System body having (a) a semimajor axis greater than that of Neptune, and (b) an absolute magnitude brighter than H = +1 (magnitude will, for the purpose of naming, be considered to be a plutoid,» so that many large and relatively round Edgeworth - Kuiper ice bodies may eventually be designated as plutoids, including 2004 XR190.

The significant radial velocity trend coupled with the imaging data indicate that the most probable orbit has a semimajor axis of about 50 AU.The discrepancy between the age indicators suggested against a bona - fide young star.
