Have you ever wondered what the asteroids orbiting our solar system look like? Curiosity about these celestial bodies continues to grow as astronomy advances and reveals surprising facts about the universe. One of the asteroids that has generated the most interest in recent years is Kassandra (sometimes written Casandra or Cassandra), formally known as (114) Kassandra. Although its name may sound like a mythical figure, it is a fascinating object whose study helps us understand the dynamics and composition of the asteroid belt.
In this article, we invite you to delve into the world of asteroids, with a special focus on Kassandra. We'll bring together up-to-date knowledge about their orbit, their history of discovery and observation, their orbital and physical characteristics, interesting facts related to their name, and how asteroids play a pivotal role in the evolution of the solar system. We'll also address the general context of current astronomy in Chile and the importance of disseminating it to understand the relevance of these bodies to science and society.
What is asteroid (114) Kassandra?
(114) Kassandra is the official name given to this minor body in the solar system, whose numerical designation indicates that it was the 114th asteroid formally registered. Discovered in the late XNUMXth century, its name pays homage to figures from Greek mythology, a common practice in asteroid cataloging.
- Kassandra It belongs to the main asteroid belt, located between Mars and Jupiter, a region populated by objects that vary greatly in size, composition and orbital dynamics.
- Kassandra's study and similar asteroids provides us with key information about the origins and evolution of the solar system, since these bodies are the 'remnants' of planetary formation.
Discovery and naming of (114) Kassandra
The asteroid was discovered on July 23, 1871 by German astronomer Christian Heinrich Friedrich Peters at Litchfield Observatory in New York City (USA). This astronomer, very prolific in the field of astronomy of his time, dedicated much of his career to the discovery and cataloging of minor bodies.
- Kassandra, like many other asteroids, takes its name from Greek mythology: Cassandra was a figure famous for her gift of prophecy and her tragic fate of not being believed.
- The choice of name demonstrates how classical culture has influenced astronomical nomenclature, giving many of these objects interesting stories and legends associated with them.
Orbital characteristics of Kassandra
Kassandra describes an elliptical orbit around the Sun within the main asteroid beltTo understand its movement and position, it is useful to know some of the parameters that define its trajectory:
- Average distance to the Sun: It is located at around 2,677 astronomical units (AU), that is, approximately 400 million kilometers from our sun.
- Maximum distance (aphelion): Kassandra may be as far away as 3,04 AU from the Sun, demonstrating that its orbit is moderately eccentric.
- Orbital inclination: Its orbital plane forms an angle of 4,936° with respect to the plane of the Earth's ecliptic, which means that it has a slightly inclined orbit compared to that of the Earth.
- Eccentricity: Its value is 0,1355, so Kassandra's orbit is notably elliptical, although not one of the most extreme within the belt.
- Orbital period: It takes approximately 1.600 days to complete a full revolution around the Sun, that is, about 4,38 Earth years.
These data are crucial for astronomers, as they allow them to understand the dynamics of the asteroid belt and calculate possible future trajectories of Kassandra.. In addition, they provide an interesting comparison with other asteroids and minor planets.
Kassandra's physical data
Main-belt asteroids can vary greatly in size, shape, composition, and albedo. According to information collected by various observatories and missions, Kassandra stands out for presenting a series of relevant physical characteristics:
- Diameter: Kassandra is estimated to be about 100 kilometers in size along its major axis, making it a medium-sized object within the main belt.
- Form: Although it is not perfectly spherical (no asteroid is truly spherical except for the most massive ones), Kassandra has a slightly elongated and irregular shape, typical of bodies of this type.
- Composition: Based on the spectra obtained, it is believed to be an S-type asteroid (silicates), although some studies suggest the possibility of metallic materials on its surface (More information about metallic asteroids).
- Albedo: The albedo, or the fraction of sunlight reflected, is intermediate: neither as dark as carbon-rich asteroids, nor as bright as pure metal ones.
Asteroids and their importance in astronomical research
Why are astronomers so interested in objects like Kassandra? Asteroids are true time capsules; their materials contain information about the conditions that existed in the early solar nebula, before and during the formation of the planets. For a deeper understanding of the topic, you can consult the origin and evolution of asteroids in our solar system.
- Study of planetary evolution: Analyzing the orbits and compositions of asteroids allows us to reconstruct the early history of the solar system and understand the processes that gave rise to Earth and other planets.
- Impacts and risks: Although Kassandra is not a near-Earth object, studying its orbits helps to identify potentially hazardous asteroids.
- Natural resources: In the future, asteroids could be mined for rare metals and minerals; Kassandra, with its rich composition, would be a good example of the possibilities offered by mining in space.
Curiosities: mythology and names in the asteroid belt
Kassandra is not a random nameThe tradition of naming asteroids after Greek or Roman mythology dates back to the early days of modern astronomy. Each name tells a story, and sometimes discoverers have chosen names with hidden or personal messages.
- Cassandra, in Greek mythology, was a Trojan princess endowed with the gift of prophecy, but condemned to have no one believe her predictions. His story symbolizes both knowledge and the frustration of not being able to share the truth.
- This name, associated with an asteroid, is evocative and fascinating, as many astronomers see the search for and study of these bodies as a way of anticipating events and discovering the secrets of the universe.

The importance of studying minor bodies: asteroids in scientific research
Asteroids, like Kassandra, are part of what astronomers call minor bodies in the solar system.These small (or not so small) objects are remnants of planet formation and, in many cases, contain materials that have barely changed in over 4.500 billion years. For more information on their role in the formation of the solar system, see .
- Current research: Analysis of the orbit, composition, and dynamics of asteroids allows us to study potential impact risks, orbital evolution, resonances, and perturbations due to the influence of gas giants like Jupiter.
- Space missions: Several international missions have approached asteroids to study them closely, take samples, and understand their internal structure and chemical composition, providing valuable data for planetary science.
- Future perspectives: The development of new technologies could enable space mining and the utilization of resources available on these objects, with both scientific and economic potential.
How the orbit of an asteroid is determined
Calculating the orbit of Kassandra and any asteroid involves the application of precise physical and mathematical principles.Astronomers observe the asteroid's position at different times and, using astrometry and celestial mechanics techniques, determine its orbital parameters. For a deeper understanding of the calculation methods, see What asteroids are and how their orbits are studied.
- The main orbital elements that are calculated are: semi-major axis (average distance to the Sun), eccentricity (measure of ellipticity), inclination (with respect to the ecliptic), perihelion argument, longitude of the ascending node y mean anomaly.
- International databases, such as the Minor Planet Center, collect and share this information for all astronomers and the interested public..
- With the development of new telescopes and automated systems, orbital parameter updating is becoming increasingly accurate.
