8.611 light years away at the speed of light. You just answered your own question. A light year is a measurement of distance not time. If something is 8.611 light years away it means it will take light 8.611 years to reach Sirius. So the answer is 8.611.
Frontal Lobe. There are four lobes in the cerebral cortex: Frontal, Parietal, Temporal and Occipital. Somatic motor cortex is in Frontal lobe , somatic sensory cortex is in Parietal lobe, auditory cortex is in temporal lobe and visual cortex is in Occipital lobe. Was this helpful?

The lowest portions of the motor cortex, closest to the temples, control the muscles of the mouth and face. The portions of the motor cortex near the top of the head control the legs and feet. Behind the frontal lobe is the parietal lobe (from a Latin word meaning wall). It includes an area called the somatosensory cortex, just behind the sulcus separating this lobe from the frontal lobe.
