Neo

Near-Earth objects (NEOs) that follow horseshoe paths, and approach our planet at close range and low relative velocity, may undergo mini-moon events in which their geocentric energy becomes negative for hours, days or months, but without completing one revolution around Earth while bound. An example of NEO experiencing such a temporarily captured flyby is 2022 NX₁, which was a short-lived mini-moon in 1981 and 2022.

Ken Bulmer pointed out that the attitude of a fan who had read much sf is different from that of a neo who is reading sf for the first time.

This fabulous fannish cover illustrated the three stages of fandom: the neo, the trufan, and the BNF.

Edwina, and neofen of her generation (this is not a criticism - everyone starts out as a neo), being new to sffandom, and not a member of faandom, would not have noticed this.

The neos seem to be no less uncomfortable with the paleos than the paleos are with the neos, […]

Some say the neos are good for what ails us on both foreign and domestic fronts, while others are quick to debate that.

The most important application of dysprosium and terbium, which belong to a subgroup known as the heavy rare earths, is in devices called neodymium boron magnets, or neo magnets for short.
