Discover the fascinating world of 704 Interamnia, the fifth largest asteroid in our solar system. Solar systemStanding out in size among its celestial neighbors, this rocky body stands in stark contrast to the smaller asteroids that populate space.

Join us as we explore this enigmatic asteroid and discover the wonders hidden within its rocky surface.

Presentation of 704 Interamnia


Italian astronomer Vincenzo Cerulli discovered 704 Interamnia on October 2, 1910, marking a significant milestone in astronomical history.


This celestial body owes its name to the Latin name for Teramo, Italy, where Cerulli worked and made this discovery.


In addition to its primary name, 704 Interamnia is also known by alternative designations such as 1910 KU and 1952 megawatts.

Key Features Explored

Main belt

704 Interamnia belongs to the main asteroid belt, which is a region between the orbits of Mars and JupiterThis asteroid is one of the largest bodies in this region.


With a average diameter of 306,313 kilometers704 Interamnia stands out for its considerable size compared to other asteroids. Its size contributes to its visibility and study by astronomers.

Spectral type

The spectral type of 704 Interamnia is classified as F/B. This classification provides information about the asteroid's composition, surface properties, and possible origins within the asteroid belt.

Rotation period

704 Interamnia has a synodic rotation period of 8.727 hourswhich indicates its speed of rotation around its axis. This rapid rotation contributes to various surface features and phenomena observed on the asteroid.

Albedo details

The asteroid exhibits a geometric albedo of 0.078which refers to the measure of how efficiently an object reflects sunlight off its surface. This low albedo value indicates that 704 Interamnia absorbs more sunlight than it reflects, which affects its temperature and overall thermal properties.

Understanding mass

Mass estimation

704 Interamnia has a The mass is estimated to be (38±13)×10^18 kgThe weight of this huge asteroid is an important factor in understanding its composition and gravitational influence.

With such a substantial mass, Interamnia exerts a remarkable gravitational pull, which affects nearby celestial bodies and orbital dynamics.

Density Perspectives

The average density of Interamnia is recorded at 2.0 ± 0.7 g/cm3This measurement provides crucial information about the asteroid's internal structure and composition.

The density of an object like Interamnia helps scientists infer its likely composition, such as the presence of metals, silicates, or other materials based on known densities.

Importance of classification

As the largest F-type asteroid discovered so far, 704 Interamnia has immense significance in the field of asteroid classification and research.

Its classification as an F-type asteroid indicates certain characteristics regarding its composition, surface features, and possible origins within the solar system. asteroid belt.

Possible former dwarf planet

Between 2017 and 2019, the Very Large Telescope's SPHERE imager made observations of 704 Interamnia. These observations, together with occultation data, suggest that Interamnia's shape could be consistent with hydrostatic equilibrium given its density and a rotation period of 7.6 hours (currently 8.7 hours).

This suggests that Interamnia may have initially formed as an equilibrium body, with impacts subsequently altering its rotation period after solidification.

This would mean that Interamnia met the requirements to be classified as a dwarf planet in the past, but no longer does so today.

Final remarks

We have uncovered the mysteries and unique characteristics of 704 Interamnia. From its massive size to the composition of its surface, you now have a clearer understanding of this intriguing asteroid. By understanding its mass and significance, you have gained valuable insights into the vast universe around us.
