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

1.9km

Mean width of the body, end to end.

≈ 18 football pitches laid end to end

Geometric albedo

02

0.38

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

Within the typical X-complex range (0.04–0.60)

Rotation period

03

2.6h

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

Spins ≈ 9.2 times in one Earth day

Absolute magnitude H

04

15.3

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

≈ 59,000× fainter than Ceres at the same distance

Orbital period

05

2.64yr

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

A year here lasts ≈ 964 Earth days

Perihelion · Aphelion

06

q1.78AU

Q2.04AU

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

Sunlight is ≈ 1.3× stronger at perihelion than at aphelion

Mean orbital speed

07

21.5km/s

Average speed along the orbit (circular approximation).

Would cross Earth’s diameter in ≈ 9.9 minutes

Inclination

08

23.1°

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

≈ 4.5× 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.

03Story

The story of Ilyra

Ilyra belongs to the Hungaria group at the inner edge of the belt, on a steeply tilted orbit. Its high albedo is typical of enstatite-rich E-types in the X-complex.

Registry note · ASR-0007

The name

Ilyra

An invented name evoking a lyre — a bright, high, tuned note.

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

X-complexMixed / enstatite

A spectral grouping that includes E (enstatite), M and P types; composition varies.

A catch-all complex of similar spectra. High-albedo members (E-types) cluster in the Hungaria region near the inner edge of the belt.

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 “Ilyra” and ID ASR-0007

Spectral class, 1.9 km diameter and Hungaria 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.
