We are Astróbriga, the astronomical group of Ciudad Rodrigo.

We have a dream: to build the first model of the solar system in three dimensions and to scale in Spain. Where? In the region of Ciudad Rodrigo.

We are talking about a solar system so large that Pluto will be on the border with Portugal. We are also talking about a comprehensive project, capable of providing economic alternatives in the area, stimulating the intellectual curiosity of youth and creating new vocations.

A project that will be the pride of the entire region.

  • The project consists of establishing a reproduction of the solar system, to scale, in the Ciudad Rodrigo region.
  • The model will not be an end in itself, but a tool to carry out activities aimed at promoting the region on a tourist level and developing educational and scientific dissemination activities in the area.
  • Not only will it be the first permanent model, in three dimensions and to scale in Spain, but it will also be, without a doubt, one of the most ambitious and complete in the world.




The Sun - With a diameter of 4.80m and composed of about 2000 brass hands, the Sun will be located in the Rotunda of the Fat Tree, and Pluto will be located about 25 kilometers away. To give you an idea, the diameter of the Sun of most of the scale models of solar systems that you can find in the world rotates between 1 and 2 meters.

The planets and their moons (15 in total) will float on monoliths made up of a Corten steel base topped by an armored glass cube. Each element of the system will be accompanied by an informative poster and a signage that will show where the other elements of the model are. The monoliths will be equipped with an internal lighting system that will allow you to visit the system at night.


A project with a pedagogical vocation

Education is one of the priority elements of the project. In fact, several teachers are actively engaged in the project.Within this framework, educational tools are being developed that educational centers will be able to use, relating astronomy to other disciplines such as physics, mathematics, visual arts, biology, history, etc ... Three educational centers in the region are officially supporting the project: the IES Fray Diego Tadeo, CEIP Miróbriga, and IESO Las Batuecas (La Alberca). Also, the Association of Tourist Guides of Ciudad Rodrigo will propose specific visits for educational centers.



Support from the scientific community

Astróbriga has the valuable support of Javier Rodriguez-Pacheco Martín (Universidad de Alcalá), Antonia Varela, (researcher at the Instituto de Astrofísica de Canarias and director of the Starlight Foundation), Sebastián Sánchez Prieto (Universidad de Alcalá), Fernando Buitrago (Instituto de Astrofísica e Ciências do Espaço de Lisboa), as well Laura Delgado Martín, Diego Corrochano Fernández, Pablo Herrero Teijón, Santiago Andrés Sánchez y Camilo Ruiz Méndez, all members of the Departamento de Didáctica de la Matemática y de las Ciencias Experimentales de la Universidad de Salamanca, they have also expressed their willingness to do outreach work within the framework of the project.

Support from other institutions

We also have the support of the Museo de Ciencias de Valladolid, la Federación Asociaciones Astronómicas de España, la Revista Astronomía, la Fundación Starlight, as well the Asociación para la Enseñanza de la Astronomía, la Organización Salmantina de Astronáutica y del Espacio or the Asociación Estudiantil de Astronomía Supernova. In addition to the Heritage Commission of the Province of Salamanca, the Ayuntamiento de Ciudad Rodrigo, FECYT, GMV and a variety of local and private companies and businesses that you can join.
