any satellites used to study more about this body?
NASA's Pioneers 6, 7, 8 and 9 ; Helios 1 and 2 probes
Sun
The first satellites designed for long term observation of the Sun from interplanetary space were NASA's Pioneers 6, 7, 8 and 9, which were launched between 1959 and 1968. These probes orbited the Sun at a distance similar to that of Earth, and made the first detailed measurements of the solar wind and the solar magnetic field. Pioneer 9 operated for a particularly long time, transmitting data until May 1983.

In the 1970s, two Helios spacecraft and the Skylab Apollo Telescope Mount provided scientists with significant new data on solar wind and the solar corona. The Helios 1 and 2 probes were U.S.–German collaborations that studied the solar wind from an orbit carrying the spacecraft inside Mercury's orbit at perihelion.
cma (canis majoris) is so bright it is visible near the rising sun but is better known as Canis Major is a constellation which contains Sirius, the brightest star in the night sky how did this bright star gets its name? Its name is derived from the Greek word "Seirios" "glowing" or "scorching". can you name a few more bright stars? Sun, Spica etc can the former be viewed by the naked eye? The brightness of the Sun can cause pain from looking at it with the naked eye; however, doing so for brief periods is not hazardous for normal non-dilated eyes how was this bright star formed? It formed approximately 4.6 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. what are the different parts of its constitution? Core, Radiative zone, Tachocline, Convective zone, Photosphere
