Physical
- Size

Orbit & access
- Orbit
- Distance from Sun: 2.85–3.28 AU; Orbital period: ≈ 5.4 years; Inclination: ≈ 15.2°; Eccentricity: ≈ 0.07 (nearly circular).Source: [1] NASA JPL Solar System Dynamics
- Accessibility (Δv / travel time)
- Model assumptionAbout 11.5 km/s of ideal Δv from low Earth orbit (5.14 km/s to depart + 6.33 km/s to arrive), and about 1.4 years for an ideal transfer.Model calculation from our Space Resource Intelligence (SRI) sample report: ideal two-impulse Hohmann transfer with a plane change, no gravity assists. Real trajectories differ.
- Mission history
- No spacecraft visit is listed in our sources. What is known comes from telescopes.
Resources & economy
- Believed resources
- Model assumptionOur model looks at water / volatiles for propellant and life support. Usable fraction assumed at 0.02–0.1 of extracted material (bear to bull). Extractable water by mass from hydrated carbonaceous material; SRI assumption, not measured for this body.SRI sample-model assumption, not a measurement.
- Economic outlook
- Model assumptionScientific value now; any resource value is long-horizon option value. Our sample model gives an NPV of about −$2,107M (bear), −$1,179M (base) and $3,276M (bull).Model output from our SRI sample valuation model (launch, product value, transit, extraction and discount-rate inputs are scenario assumptions, not forecasts). Not investment advice.
