Explore Alliance Ambassadors - Nicole Semião

Nicole Semião is a shining example of how curiosity and passion for space can ignite a lifelong journey of exploration and discovery. Her fascination with asteroids began at the age of eight, when she first looked to the stars and wondered about the mysterious celestial bodies orbiting our solar system.

From the beginning, Nicole demonstrated a natural affinity for science and astronomy. Her interest in asteroids—particularly their composition, behavior, and potential impact on Earth—quickly grew into a focused pursuit. With the support of her family and educators, she immersed herself in books, online resources, and hands-on tools like telescopes, laying the foundation for her independent research.

Nicole’s dedication to understanding asteroids led her to connect with mentors and professionals in the field, many of whom recognized her potential and offered guidance. Through these relationships, she deepened her knowledge and began contributing meaningfully to the scientific community, exploring topics such as planetary defense and asteroid mining.

As she progressed academically, Nicole actively participated in science fairs, space-related competitions, and collaborative projects with other young explorers. Her achievements earned her recognition at local, regional, and national levels, along with scholarships and awards that further fueled her passion.

Nicole Semião’s story embodies the spirit of the Explore Alliance—a commitment to curiosity, lifelong learning, and the power of community in advancing space science. Her journey continues to inspire young astronomers and explorers around the world, proving that age is no barrier to making a meaningful impact in the quest to understand our universe.

Asteroid 292352 Nicolinha (2006 SU218)

The asteroid 292352 Nicolinha was first discovered on September 26, 2006, by astronomer Robert E. Holmes Jr. in Charleston, Illinois. Nearly two decades later, it was officially named “Nicolinha” to honor Nicole Oliveira Semião—affectionately known as Nicolinha—a young Brazilian science communicator from Alagoas, born in 2012, whose passion for astronomy has inspired people around the world.

Nicolinha’s Story

• Nicolinha, recognized as the world’s youngest research astronomer, has displayed passion and talent in astronomy since around age six. She’s discovered dozens of asteroids through citizen-science initiatives.

• She’s a science outreach ambassador in Brazil and has inspired many with her workshops, YouTube content, and public outreach.

• The asteroid’s naming is a tribute to her remarkable achievements in promoting astronomy and citizen science among youth.

Orbital Placement

• Nicolinha resides within the main asteroid belt located between Mars and Jupiter.

• Detailed orbital parameters (like semi-major axis, eccentricity, and orbital period) are likely available via NASA’s JPL Small-Body Database or the Minor Planet Center for even deeper insights—feel free to ask if you’d like that data!
