Spring Break

During spring break I hung out with friends, spent time with family, and went shopping. The worst part about spring break is going back to school.

Comet, Asteroids, Meteors, and Moons

Comets, Asteroids, Meteors and Moons

            A comet is a small, icy celestial body that orbits around the sun. It is made up of a nucleus. Nucleus is made of solid, frozen ice, gas and dust. A gaseous coma is made of water vapor, CO2, and other gases, and a long tail made of dust and other gases. The tail develops when the comet is near the Sun. Its long tail that always points away from the sun, because of the force of the solar wind. The tail can be up to 250 million km long. Comets are only visible when they're near the sun in their highly eccentric orbits.

            Asteroids are rocky and metallic objects that orbit the Sun but are too small to be considered planets. They are known as minor planets. Asteroids range in size from Ceres, which has a diameter of about 1000 km. Sixteen asteroids have a diameter of 240 km or greater. They have been found inside Earth's orbit to beyond Saturn's orbit. However, are contained within a main belt that exists between the orbits of Mars and Jupiter. Some have orbits that cross Earth's path and some have even hit the Earth in times past.

            The term meteor comes from the Greek meaning phenomenon in the sky. It is used to describe the streak of light produced as matter in the solar system falls into Earth's atmosphere. This typically occurs at heights of 80 to 110 kilometers which is 50 to 68 miles above Earth's surface.  A meteoroid is matter revolving around the sun or any object in space that is too small to be called an asteroid or a comet. Even smaller particles are called micrometeoroids, which includes any interstellar material that should happen to enter our solar system. A meteorite is a meteoroid that reaches the surface of the Earth without being completely vaporized.

            The Moon is the most noticeable object in the night sky. If you observe it for several days, you will no doubt notice that its appearance changes, most of the time. One possible explanation that comes to mind is that the dark part we see on the Moon is the shadow that the Earth casts on it. If this were true, the Moon should be in its new phase when it at its farther from the Sun. We know when this happens, because then the Moon rises at the same time as the Sun sets. Besides, if the Moon passes through the Earth's shadow every month, then when it is at the opposite side of its orbit it should get directly in between the Sun and the Earth, producing a solar eclipse much more often than it actually happens.

            All of these words, Comets, Asteroids, Meteors, and Moons all have different meanings in them. They might come from the same place but they still are all different in some way shape or form.

Milky Way Proficency

Milky Way Galaxy

Ever wondered what galaxies really are? When you hear about the Milky Way, do you think of the candy bar? Or do you think of the galaxy that harbors thousands of stars? There are specific types of galaxies in the universe. They are known as Elliptical, and Irregular galaxies. They all are different, yet the same in many ways.

Elliptical Galaxy, these galaxies are much larger than any other galaxy in the solar system. This Galaxy does not rotate.  They just stand still in space. This galaxy also does not make many stars, because of there is not a lot gas and dust. Almost all of the stars are very old. These galaxies have no disk, but instead a bulge in the center, which is not always round.  And a halo that is brighter towards the middle and gets dimmer as you get closer to the outside.

Irregular Galaxy is the rarest galaxy known. This galaxy is known as the “leftover” galaxy. Usually these galaxies are created, when two or more galaxies collide with each other.  Every type of Irregular galaxy is different. So you can’t say if they always have a bulge, halo, or disk. They usually do not rotate. Some Irregular galaxies can be thousands of years old, and some others could be millions. 

The Milky Way is known as our galaxy. This is a Spiral Galaxy. And is the only galaxy that is visible from Earth. Yet is still smaller than a lot of Elliptical Galaxies. This Galaxy has a lot of dust and gas, and is constantly making stars. The Milky Way is estimated to be almost as old as the Universe.  Which is 13.7 billion years old. Also, this huge galaxy is always made of many different galaxies made into one.

Story

The main character for my story is going to be Abraham Lincoln. It is going to be about his death and about how  his life was until the day he died. 

The main point of my book was about Abraham Lincoln's death.
