Abstract: Analysis of energy distributions in the range of 0.36–18 μm and high-resolution spectra showed that the brightest stars of the Orion Trapezium are multiple systems, in which the primaries are young massive OB stars, spectral types of secondary components are late K–M stars and/or dust provide IR-radiation. In the Θ1Ori C system, A0 stars were found escaping it in opposite directions. Parameters of the components, elements of their orbits, and evolutionary status were determined.
