T-TIuiri star A young star that is approaching the main sequence on the Hertzsprung-Russell diagram, terrestrial planets Solar system planets that are relatively small and dense compared with the gas giants, including Mercury, Venus, Earth, and Mars sometimes referred to as the minor planets. 

Spectroscopic observations of Jupiter and Saturn made with the Infrared Space Observatory are consistent with other estimates of protosolar D/H (see Robert et al. 2000 and references therein), as is the D/H value determined by the Galileo atmospheric entry probe mass spectrometer (26 7 ppm Mahaffy et al. 1998). This result is expected as the jovian planets are thought to have formed by quantitative capture of gas from the solar nebula. On the other hand, the outer solar system planets Uranus and Neptune appear to be significantly enriched in D/H by factors of -3 compared to the protosolar value (Feuchtgruber et al. 1999). This enrichment is interpreted to reflect the mixing of material from the more D-rich icy cores of these planets, which constitutes a significant fraction of their mass (as opposed to the jovian case where the planetary mass is dominated by the gaseous envelope).

Finally, we note that both synchrotron and cyclotron radiation from (solar system) planets is confined to the radio region of the spectrum. This circumstance is due to the range of planetary magnetic field strengths and particle energies found in the solar system. The existence of Jupiter s strong magnetic field was first deduced from earth-based measurements of its polarized radio emission.
