    • Location: 55 Cancri E in the Constellation of Cancer
    • 55 Cancri e is an extrasolar planet approximately 40 light years from Earth orbiting the Sun-like star 55 Cancri A. Its mass is about 7.8 Earth masses and its diameter is about twice that of Earth's, thus classifying it as the first Super-Earth discovered around a main sequence star. 55 Cancri E is believed to be a solid planet made of carbon-rich material rather than the oxygen-rich material that makes up the terrestrial planets in our solar system. As such, roughly a third of the planet's mass would be carbon. Due to conditions in the planet’s atmosphere, much of this mass may be diamond.

    Challenge Description:

    Encourage space education and awareness by designing a piece of jewelry or wearable art that celebrates 55 Cancri E’s unique qualities.

    Functional Specifications:

    Open to definition, but could include:

    • A playful art/jewelry project that engages children and those without technological skills to celebrate 55 Cancri E.
    • Jewelry/wearable art that celebrates 55 Cancri E via a diamond motif.
    • Digital jewelry that orients 55 Cancri E’s location or celebrates its unique qualities, possibly leveraging Arduino/GIS technology.
