Small Very Fast Rotating (VFR) asteroids (bodies with rotation periods as short as 25 sec) are consistent with a population of strange asteroids [with quark dark matter] with core masses of order 10^10 – 10^11 kg.. Those would then be sources of millions of tons of antimatter for future spaceships.

Macroscopic quark matter nuggets are an alternative explanation for Dark Matter (DM) consistent with the observational constraints on this mysterious cosmological component. Such quark matter theories have strong implications in the formation, development and current behavior of the Solar System, as primordial quark nuggets orbiting the Galaxy would be subject to capture during planetary formation, leading to the retention of condensed quark matter in the centers of the Sun, planets and asteroids today, a possibility that needs to be taken seriously in Solar System Research.
As quark nuggets are expected to have a minimum mass set by their physics of their formation, any sufficiently small asteroid with a quark matter core would be a strange asteroid, with a high bulk density and strong gravitational binding. Small strange asteroids would be the easiest nugget hosts to detect observationally, and the most accessible source of quark matter once detected. Solar System observations of small Very Fast Rotating (VFR) asteroids (those with rotation periods ≤ 1/2 hour) support the quark matter nugget hypothesis. If VFR asteroids are assumed to be bound by quark matter cores, the inferred core mass range peaks at ∼10 billion kg, consistent with the stable quark matter mass range predicted by the detailed theory of Zhitnitsky an
d his colleagues.
As there is a prospect that quark nuggets could be used to produce large amounts of antimatter, the economic benefit from even a single ultra-dense strange asteroid could be little short of astounding. If some of the Near-Earth Objects (NEO) are indeed strange asteroids they would truly constitute a game-change resource for space exploration. It is likely that the quark nugget theory will either be rapidly refuted using Solar System observations, or become a focus of space exploration and development in the remainder of this century
There have been numerous suggestions that macroscopic ultra-dense objects, either quark nuggets or Primordial Black Holes (PBH), formed in the early universe, persisted until the present, and provide the Dark Matter (DM) required by a variety of astrophysical and cosmological observations. An important check on these DM theories comes from the condensed object mass spectrum, observational estimates of space density or flux compared to the known DM density. The three conventional checks on macroscopic DM, observations of the flux through laboratory detectors, planetary detectors and ground-based gravitational microlensing surveys, allow two disjoint mass regions for viable macroscopic DM particle masses. New Kepler satellite microlensing data restrict the allowed DM region somewhat, while a search for femtolensing of Gamma Ray Bursts (GRBs) provides a new set of DM constraints, greatly restricting the allowed region for larger masses and leaving three allowed “windows” in the mass spectrum. Combining all of these constraints, DM made up exclusively of a particle of mass M DM would not violate current observational constraints if 6 × 10^−6 kg ≤ MDM ≤ 10 kg, or 10^5kg ≤ M DM ≤ 10^18 kg, or 10^20 kg ≤ MDM ≤ 10^22kg.
Although Dark Matter (DM) apparently pervades the universe, it is rarely considered in the context of the formation of the Solar System and other planetary systems. However, a relatively small but non-negligible fraction of the mass of any such systems would consist of DM gravitationally captured during the collapse of the proto-planetary Nebula, subject to the very general assumption that DM particles have an individual mass
