Yes, Earth does have a corona, but it is not the same as the solar corona. Earth's corona is a rarefied layer of gases surrounding the planet, primarily composed of hydrogen and helium. This outermost layer of Earth's atmosphere extends into space, gradually thinning out as it merges with the solar wind.
Earth is bigger than the moon, but that has absolutely nothing to do with the sun's corona.
Because the sun, Earth, and the moon line up in a strait path with the Earth in between. The corona is the earth's shadow on the moon.
Past Earth's orbit
From Earth, the Photosphere is the part visible on the Sun, though the Corona is the top layer of the Sun. We cannot see the Corona because the Photosphere is so bright.
The effects to the economy after the impeachment of Chief Justice Corona should be minimal to none. Chief justices usally do not play a major part in the structure of an economy and a new justice will be established anyway.
During a solar eclipse.
It has been seen that intense corona effects are observed at a working voltage of 33 kV or above.Therefore, careful design should be made to avoid corona on the sub-stations or bus-bars rated for 33kV and higher voltages otherwise highly ionised air may cause flash-over in the insulators or between the phases, causing considerable damage to the equipment. The corona effects can be reduced by the following methods :(i) By increasing conductor size. By increasing conductor size, the voltage at which corona occurs is raised and hence corona effects are considerably reduced. This is one of the reasons that ACSR conductors which have a larger cross-sectional area are used in transmission lines.(ii) By increasing conductor spacing. By increasing the spacing between conductors, the voltage at which corona occurs is raised and hence corona effects can be eliminated. However, spacing cannot be increased too much otherwise the cost of supporting structure (e.g., bigger cross arms and supports) may increase to a considerable extent.
the corona affects the earth the most
Photosphere, chromosphere, and corona
Because the Sun's photosphere is so much brighter in visible light (most of the light the Sun's corona emits is ultraviolet). It is necessary to block the light from the Sun's photosphere to see the Sun's corona.
Because in a full eclipse the moon is close enough to the earth to block all the sun's disk and the light of this disk does not visually hide the corona. In an annular eclipse the moon is farther from the earth and not all of the sun's disk is blocked so there is enough light escaping around the block to hide the corona. .
