If a newly discovered celestial object orbits the Sun, is nearly round, but shares its orbital space with numerous other objects, how would it MOST likely be classified?
If a newly discovered celestial object orbits the Sun, is nearly round, but shares its orbital space with numerous other objects, how would it MOST likely be classified?
- A large asteroid, due to its shared orbital space.
- A moon, provided it orbits another planet within the solar system.
- A planet, as it meets two of the three criteria.
- A dwarf planet, as it hasn't cleared its orbit. (correct)
Which of the following BEST explains why comets develop tails as they approach the Sun?
Which of the following BEST explains why comets develop tails as they approach the Sun?
- The comet's internal nuclear reactions intensify.
- The Sun's gravity pulls material off the comet's surface.
- The solar wind vaporizes the comet's icy materials. (correct)
- The comet reflects more sunlight as it gets closer.
The phrase "My Very Excited Mother Just Served Us Nachos" is a mnemonic for remembering the order of planets. What aspect of planetary order does this mnemonic MOST accurately represent?
The phrase "My Very Excited Mother Just Served Us Nachos" is a mnemonic for remembering the order of planets. What aspect of planetary order does this mnemonic MOST accurately represent?

Study Notes
-
Our solar system is centered around the Sun.
-
The Main Asteroid Belt is located between Mars and Jupiter.
-
Pluto is classified as a dwarf planet.
-
A moon is a celestial body that orbits a planet.
-
Producing its own light is NOT a requirement to be considered a full-sized planet.
-
"My Very Excited Mother Just Served Us Nachos" is a mnemonic to remember the order of the planets in the solar system.
-
An asteroid is a small, rocky object that orbits the Sun, mostly found in the asteroid belt.
-
A comet is an icy celestial body that develops a glowing tail when it gets close to the Sun.
-
The International Space Station (ISS) is an artificial satellite that orbits Earth, allowing astronauts to conduct research.
-
Alberta's first satellite was called AlbertaSat-1.
-
The Sun is NOT a planet (False).
-
Not all celestial bodies emit their own light (False).
-
Satellites can be natural or artificial (False).
-
Probes are spacecraft that travel to distant celestial bodies without human passengers (True).
-
Living in space is NOT easy because there are environmental challenges (False).
-
A natural satellite is a celestial body that orbits a planet or other body, while an artificial satellite is human-made and launched into orbit.
-
Technologies used to explore space include telescopes, satellites, probes, and manned spacecraft.
-
Astronauts experience muscle loss in space due to the lack of gravity.
-
Societal barriers to space exploration include funding limitations, international cooperation challenges, and ethical concerns.
-
Meteors emit light when they enter Earth's atmosphere due to friction with the air, causing them to heat up and burn.
-
The largest planet in our solar system is Jupiter.
-
The four inner (terrestrial) planets of the solar system are Mercury, Venus, Earth, and Mars.
-
Pluto was reclassified as a dwarf planet because it has not cleared its orbit of other objects.
-
The Sun is a star.
-
One challenge astronauts face when living on the ISS is the lack of gravity, which can cause health problems.
