Solar System
This is the percentage of mass in the solar system that the Sun makes up.
What is 99.8% of the mass in our solar system?
What is a rocky core?
This is an artificial satellite that serves as a multi-country hub for scientific research.
What is the International Space Station (ISS)?
What is they contain ice?
These space probes were sent to explore the outer planets of the solar system and send information back to Earth.
What are Voyager 1 and 2?
These are the two categories of planets found in our solar system.
What are terrestrial planets and gas giants?
The period in which a planet travels fastest in its orbit is called this.
What is perihelion?
This is the name for natural satellites found orbiting asteroids.
What is a moonlet?
This is the correct order in increasing size of comet, meteoroid, planet, dwarf planet, and asteroid.
This space technology is used to orbit around celestial objects and study information about the objects.
What are orbiters?
This is the furthest boundary that defines our solar system.
What is the Oort Cloud?
These are the requirements for a celestial object to be a planet.
What is:
1) must orbit a star,
2) have enough mass to be pulled into a sphere by gravity, and
3) dominate its orbit
This is the term for when a satellite completes one orbit around the Earth in exactly one day.
What is a geosynchronous orbit?
This is the difference between a meteor, a meteoroid, and a meteorite.
Meteoroid - In space
Meteor - crashing through the atmosphere
Meteorite - has hit the surface
This was the first space telescope.
What is the Hubble Space Telescope?
This region of the solar system contains dwarf planets, comets, asteroids, meteoroids, ice, and dust.
What is the Kuiper Belt?
What is gas giants have larger cores, meaning they have larger gravitational forces?
These are the 3 major categories of uses for artificial satellites.
What is scientific research, surveillance, and Global Positioning System (GPS)?
This is the tail of a comet that is affected by solar winds.
What is the gas tail?
These are sometimes referred to as laboratories on wheels.
What are rovers?
A star died and exploded, sending matter out into space. Over time, gravity brings the matter back together into a star and creates a rotating disk of remaining gases and dust to form the planets.
This is Kepler's Third Law of Planetary Motion.
What states there is a direct relationship between the length of a planet's year and its distance from the Sun? (i.e., the closer the planet to the Sun, the shorter the year)
This planet has the most natural satellites. This is the number of natural satellites.
You need to get both answers correct to get the points.
What is Saturn and its 274 moons?
This is what causes a meteor shower.
What is Earth passing the same spots of debris in space?
Salyut 1 was the first of its kind, being a habitable structure in space. This is the name of that type of structure.
What is a space station?
