Answer 1

Answer:

1. planet - A planet is a large object such as Venus or Earth that orbits a star. Planets are smaller than stars, and they do not produce light. Jupiter is the biggest planet in the Solar System.

Planets are shaped like a slightly squashed ball (called a spheroid). Objects that orbit planets are called satellites.

2. Meteors - A meteor is what you see when a space rock falls to Earth. It is often known as a shooting star or falling star and can be a bright light in the night sky, though most are faint. A few survive long enough to hit the ground. That is called a meteorite

3. Sphere - Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). Each of these four spheres can be further divided into sub-spheres.

4. Equator - The Equator is an imaginary line around the middle of the Earth. It is halfway between the North and South Poles, and divides the Earth into the Northern and Southern Hemispheres.

5. Tailed star - A tailed star is also known as comets. A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produce a visible atmosphere or coma, and sometimes also a tail.

6. Astroids - Asteroids are actually minor planets which can neither be classified either as a planet or as a comet. These are generally in the direct orbit around the Sun, also known as the inner solar system. The larger forms of asteroids are also known as planetoids.

7. Lunar eclipse - A lunar eclipse occurs when the Moon moves into the Earth's shadow.[1] This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, and only on the night of a full moon. The type and length of a lunar eclipse depend on the Moon's proximity to either node of its orbit.

8. Axis - An axis is an imaginary line that passes through the origin point of a geometric coordinate system. ... For every point on an axis, the value of every other dimensional coordinate is zero. For example, in a two-dimensional space, every point on the X-axis has a Y-coordinate value of zero.
