• The word 'NEO' is used to refer to an object with an orbit that takes it close to Earth.

• The object was believed to be an alien object because its velocity is smaller than that of the earth. Even, owing to the observance of the solar radiation pressure.

• Solar Radiation Strain is found in all celestial bodies that are closer to the radiation of the sun. It's smaller in the satellites.
