1. What is the significance of the ecliptic? Why are
the sun, the moon, and the planets only found near the
ecliptic?
2. What is the difference between a constellation and asterisk?
Give two examples of each
1. Ans Significance :The ecliptic is the mean plane of the apparent path in the Earth's sky that the Sun follows over the course of one year, it is the basis of the ecliptic coordinate system. This plane of reference is coplanar with Earth's orbit around the Sun.
Because the orbit of the Moon is inclined only about 5.145° to the ecliptic and the Sun is always very near the ecliptic, eclipses always occur on or near it. Because of the inclination of the Moon's orbit, eclipses do not occur at every conjunction and opposition of the Sun and Moon, but only when the Moon is near an ascending or descending node at the same time it is at conjunction or opposition. The ecliptic is so named because the ancients noted that eclipses only occurred when the Moon crossed it
Reason : The orbits of the planets are coplanar because during the Solar System's formation, the planets formed out of a disk of dust which surrounded the Sun. Because that disk of dust was a disk, all in a plane, all of the planets formed in a plane as well.
Rings and disks are common in astronomy. When a cloud collapses, the conservation of angular momentum amplifies any initial tiny spin of the cloud. As the cloud spins faster and faster, it collapses into a disk, which is the maximal balance between gravitational collapse and centrifugal force created by rapid spin. The result is the coplanar planets, the thin disks of spiral galaxies, and the accretion disks around black holes.
2. Ans Constellation : A constellation is a group of stars that forms an imaginary outline or pattern on the celestial sphere, typically representing an animal, mythological person or creature, a god, or an inanimate object.
Asterisk: Stars in night sky.

1. All the planets orbit the Sun in the same direction. This is strong evidence that: Group of answer choices None of these is correct. We do not have any idea yet why the planets are orbiting in the same direction. the solar system resulted from the collision of two medium-sized stars. after the planets formed, collisions between them eventually caused them all to move in the same direction. the planets were formed elsewhere in the galaxy and were later...
The author mentions in one place that the Moon is approximately 60 Earth radii away. In another place he says the Moon is about 10 times the Earth's girth away (in this case, girth really means "how far around") Without looking up the numbers for the Earth's size or the real distance to the Moon, show that these two statements are roughly consistent with each other. Describe why this is true. Why are the planets close to the Sun in...
