ABSTRACT The (153591) 2001 SN263 asteroid system, a target of the first Brazilian
interplanetary space mission, is one of the known three triple systems within the population …

The objective of the present paper is to investigate the zero velocity curves, using the Jacobi
constant CC, and to determine the positions of the libration points in the restricted …

Stability for the non-autonomous bicircular four-body model is analytically investigated in
this study. The governing equation is derived from Newton's law of gravity. When the …

The Aster mission is the first proposed Brazilian deep space mission. The target is the triple
near-Earth asteroid (153591) 2001 SN 263. This work searches for less-disturbed orbital …

The goal of the present manuscript is to determine the points of libration and their linear
stability in the elliptic restricted synchronous three-body problem with a mass dipole model …

The strongly perturbed environment of a small body, such as an asteroid, can complicate the
prediction of orbits used for close proximity operations. Inaccurate predictions may make the …

The main goal of this paper is to search for orbits that can be used in the Brazilian proposed
Aster mission. This mission is under study and its objective is to use a spacecraft to observe …

We search for stable orbits in the vicinity of the triple asteroid system, 2001-SN263, which
will be target of the deep space mission ASTER, currently under study by the Brazilian space …

Abstract Space missions allow us to expand our knowledge about the origin of the solar
system. It is believed that asteroids and comets preserve the physical characteristics from …

The goal of this paper is to develop a simplified model to describe the gravitational fields of
elongated asteroids. The proposed model consists of representing an elongated asteroid …
