The sun resides some 26,000 light-years away
from the Milky Way's centre, in a tendril of the
home galaxy known as the Orion Arm.
Formed more than 4.5 billion years ago, when
a cloud of dust and gas called nebula collapsed
under its own gravity, the sun, holds the solar
system together; providing life-giving light,
heat and energy to Earth, and generating space
weather.
For a fact, it takes eight minutes and 20
seconds for the light leaving the sun to reach
Earth. Also, looking directly at the sun with
naked eyes can damage eyesight.

The Moon is an astronomical body orbiting Earth and is the planet's only natural satellite. It is the fifth-largest satellite in the Solar System, and by far the largest among planetary satellites relative to the size of the planet that it orbits.
Distance to Earth: 384,400 km
Gravity: 1.62 m/s²
Radius: 1,737.1 km
Orbital period: 27 days
Surface area: 3.793×107 km2; (0.074 of Earth's)
Alternative names: Luna; Selene (poetic); Cynthia (poetic)
Explanation:
Answer:−
☞ An azo coupling is an organic reaction between a diazonium compound and another aromatic compound that produces an azo compound.
☞ Examples of azo C-coupling reactions. Phenol reacts with benzenediazonium chloride to give a Solvent Yellow 7, a yellow-orange azo compound. The reaction is base-catalysed. The related dye called aniline yellow is produced from the reaction of aniline and the diazonium salt.
