Earth trailing heliocentric orbit
http://www.spitzer.caltech.edu/about/orbit.shtml WebApr 10, 2024 · Wang et al. [13] proposed a deployment design with two telescopes in heliocentric orbit approximately 10 million kilometers ahead of the Earth, and NEOs approaching the Earth from the Sun can also be detected. Some scholars investigated the assessment of NEOs using distant retrograde orbits (DROs) [14], [15].
