01Vital statistics

Measured in light and motion

Each figure is catalogued or derived from the orbit with standard formulas — period from Kepler's third law, brightness from size and albedo. Preview data until verification.

Orbits explainedSpectral classes

Diameter

01

0.42km

Mean width of the body, end to end.

≈ 4 football pitches laid end to end

Geometric albedo

02

0.27

How reflective the surface is, compared with an ideal white disc.

Within the typical S-type range (0.10–0.30)

Rotation period

03

2.9h

The length of its day — one full spin on its axis.

Spins ≈ 8.3 times in one Earth day

Absolute magnitude H

04

18.9

Intrinsic brightness, from size and albedo. Lower is brighter.

≈ 1,700,000× fainter than Ceres at the same distance

Orbital period

05

2.06yr

One lap around the Sun, from Kepler’s third law.

A year here lasts ≈ 753 Earth days

Perihelion · Aphelion

06

q0.87AU

Q2.37AU

Closest and farthest distance from the Sun. 1 AU is the Sun–Earth distance.

Sunlight is ≈ 7.3× stronger at perihelion than at aphelion

Mean orbital speed

07

23.4km/s

Average speed along the orbit (circular approximation).

Would cross Earth’s diameter in ≈ 9.1 minutes

Inclination

08

5.4°

Tilt of the orbit against the ecliptic, the plane of Earth’s orbit.

About the tilt of the Moon’s orbit (5.1°)

02Orbit

Its path around the Sun

Drawn to scale with the Sun at one focus. The body moves by Kepler's equation — fast near the Sun, slow far from it — while the planets keep their true relative pace.

Earth-crossing, with a semi-major axis larger than Earth's (a > 1 AU, perihelion < 1.017 AU).

03Story

The story of Helion Drift

An Apollo-class near-Earth asteroid whose perihelion carries it inside Earth's orbit. Small, quick, and sunlit — a visitor that keeps coming back.

Registry note · ASR-0005

The name

Helion Drift

From helios, the Sun — for an orbit that dives inside Earth's.

An Asteria registry name. Official minor-planet names are approved by the IAU's Working Group Small Bodies Nomenclature and cannot be bought. Registry vs official names

Composition

S-typeSilicaceous

Stony silicates (olivine, pyroxene) mixed with nickel-iron metal.

Bright, stony bodies that dominate the inner main belt. Many ordinary-chondrite meteorites found on Earth are linked to S-type parents.

Typical S-type albedoThis body
Spectral classes, explained
04Certificate

A certificate for the name

At launch, each registry entry is planned to come with a digital certificate. This live preview is built from this entry's data.

Registry name “Helion Drift” and ID ASR-0005

Spectral class, 0.42 km diameter and Apollo orbit

An optional personal dedication line

A reference to the token that records it (planned)

Preview render — final design subject to change. A certificate records an Asteria registry name; it is not an IAU designation and does not convey ownership of the asteroid.
