Thalassa Veil

From thalassa, the sea — for a body adrift in Jupiter's wake.

Official designation: pending verificationRegistry name, not an IAU name

Procedural illustration — not a measured shape

It shares an orbit with Jupiter.

Indicative launch price

3.5 ETH

Planned for the launch sale.

Indicative only and not an offer. Currency, final price and fees are planned and subject to legal review.

Marketplace opens in Phase 3 — join the waitlist. Tokens are digital collectibles and registry entries; they convey no ownership of the asteroid.

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

24.5km

Mean width of the body, end to end.

≈ 233 football pitches laid end to end

Geometric albedo

02

0.06

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

Within the typical D-type range (0.02–0.08)

Rotation period

03

11.3h

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

Spins ≈ 2.1 times in one Earth day

Absolute magnitude H

04

11.7

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

≈ 2,300× fainter than Ceres at the same distance

Orbital period

05

11.89yr

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

A year here lasts ≈ 4,344 Earth days

Perihelion · Aphelion

06

q4.90AU

Q5.52AU

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

13.0km/s

Average speed along the orbit (circular approximation).

Would cross Earth’s diameter in ≈ 16.3 minutes

Inclination

08

17.5°

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

≈ 3.4× 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 Thalassa Veil

A Jupiter Trojan riding the giant planet's orbit near a Lagrange point, five times farther from the Sun than Earth. Dark, reddish and primitive — a relic of the outer Solar System.

Registry note · ASR-0009

The name

Thalassa Veil

From thalassa, the sea — for a body adrift in Jupiter's wake.

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

D-typePrimitive red

Very dark, reddish material thought to be rich in organics and ices.

Dark, red bodies common among Jupiter Trojans and in the outer belt — likely formed far from the Sun.

Typical D-type albedoThis body

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 “Thalassa Veil” and ID ASR-0009

Spectral class, 24.5 km diameter and Jupiter Trojan 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.
05Token metadata

This is the metadata a token for this entry would carry when minting opens. Nothing has been minted yet.
