Explanation

A constellation is a group of stars forming a pattern, located outside our solar system.

Asteroids, satellites, and comets are all within the solar system.

Explanation

Inner Solar System:

Includes the four rocky planets:

Mercury, Venus, Earth, Mars

These are closer to the Sun, have solid surfaces, and are also called terrestrial planets.

Outer Solar System:

Includes the gas giants and ice giants:

Jupiter, Saturn, Uranus, Neptune

These planets are larger, farther from the Sun, and composed mostly of gas or ice.

So, Jupiter is not part of the inner solar system.

Explanation

Earth, Mars, and Pluto have atmospheres that contain Nitrogen gas.

• Earth: ~78% nitrogen
• Mars: ~2.6% nitrogen
• Pluto: thin atmosphere with nitrogen ice and gas

Neptune's atmosphere is mostly hydrogen, helium, and methane, not nitrogen.

Explanation

The main idea of the solar system was proposed by the Polish astronomer Nicolaus Copernicus (1473-1543).

who said that "the Sun is the centre of the Universe" and made the planets move around it in perfect circles

(in his book entitled, "On the Revolution of the Celestial Spheres", written in Latin and published in 1543)

Explanation

The galactic bulge is the bright, dense center of a spiral galaxy.

It contains old stars.

It often a supermassive black hole at the core.

Explanation

Asteroids are also called "minor planets".

They are small, rocky bodies that orbit the Sun, often between Mars and Jupiter.

They are considered remnants from the formation of the solar system and are not large enough to be classified as a planet. 

"asteroids" (possibly what "altereds" was meant to be)

Explanation

• The asteroid belt is a region of space where many small rocky bodies, called asteroids, orbit the Sun.
• It's also known as planetoids or minor planets.
• It is located between the orbits of Mars and Jupiter, spanning from about 2.2 to 3.2 astronomical units (AU) from the Sun.
