This is a NASA image of two meteors falling to Earth during the Perseids meteor shower. If you like to watch such events, you kn
ow that astronomers can predict when during the year specific meteor showers will occur. Explain how astronomers can make these
predictions. All of the choices EXCEPT one will help with your explanation.
A)
Every Perseid meteor is a tiny piece of the comet Swift-Tuttle.
B)
Meteor showers are visible only in the northern hemisphere as the comets
orbit over the Earth.
Meteor showers occurs at regular intervals as the Earth passes through the
trail of debris left by a comet.
D)
Meteor showers are usually named after a star or constellation that is close
to where the meteors appear in the sky.
B)Meteor showers are visible only in the northern hemisphere as the comets orbit over the Earth.
Explanation:
Meteor showers are visible only in the northern hemisphere as the comets orbit over the Earth. Stars and constellations appear throughout the sky, in both hemispheres. Meteors are visible everywhere, although some showers are more visible in certain parts of the night sky at specific times during the year.
The Anters is on the average the 15 brightest stars found in the constellation of the Scorpius and is a distinction reddish when viewed from the sky and being as a low irregular variable star is visible on the 31 May of each year. The Antares is 4.5 degrees south to the ecliptic and one of the four first magnitude stars within 6° angle and represents a 27 stars that are arranged in a unit of Brazil.
