what makes uranus move at such a slow speed UNANSWERABLE what is this planetary body? It is the seventh planet from the Sun. who was the first to identify it? Possibly the earliest known observation was by Hipparchos. where did it get its name from? It's name references the ancient Greek deity of the sky Uranus. how hot is the interior of it? It's internal heat appears markedly lower than that of the other giant planets what is the size of the star mentioned above that it revolves around? Its diameter is about 109 times that of Earth. does it give out any radiation? From the core out to about 0.7 solar radii, thermal radiation is the primary means of energy transfer.

Sun [SEP] Core
The proton–proton chain occurs around times each second in the core, converting about 3.7 protons into alpha particles (helium nuclei) every second (out of a total of ~8.9 free protons in the Sun), or about . Fusing four free protons (hydrogen nuclei) into a single alpha particle (helium nucleus) releases around 0.7% of the fused mass as energy, so the Sun releases energy at the mass–energy conversion rate of 4.26 million metric tons per second (which requires 600 metric megatons of hydrogen ), for 384.6 yottawatts (), or 9.192 megatons of TNT per second. The large power output of the Sun is mainly due to the huge size and density of its core (compared to Earth and objects on Earth), with only a fairly small amount of power being generated per cubic metre.
