What astronomy tool collects visible light, then uses convex lenses to focus the light producing larger, brighter images of distant objects in space.

• Reflecting telescope

• Refracting telescope

• Radio telescope

• Infrared telescope

What astronomy tool collects visible light, then uses mirrors to focus the light producing larger, brighter images of distant objects in space.

• Reflecting telescope

• Refracting telescope

• Radio telescope

• Infrared telescope

What do you call astronomy tools placed in orbit around Earth. They have special instruments and telescopes that collect information from space. This information is sent back to Earth where it is interpreted.

• Satellite
• Space Probe
• Radio telescope
• Spectroscope

What do you call the astronomy tool that receive radio waves emitted from objects in space, including waves from very distant stars and galaxies; it can receive information in any weather and during day or night.

• Radio telescope
• Spectroscope
• Space probe
• Infrared telescope

What do you call the astronomy tool that collects light from distant stars and separate that light into bands of different colors; by studying these bands, astronomers can identify the elements, density, and temperature of distant stars and perhaps planets.

• Space Probe
• Spectroscope
• Infrared telescope
• Satellite

What do you call the astronomy tool that contains specialize instruments to collect data. They often travel out of Earth’s orbit to explore places that would be too dangerous for humans.

• Space Probes
• Spectroscope
• Satellites
• Space Shuttle

What do you call the amount of matter in an object. It remains the same regardless of an object's location.

• Mass
• Weight
• Gravity
• Force

What do you call the measure of gravitational pull on an object. (Mass times gravity) This changes depending on the objects location.

• Gravity
• Mass
• Weight
• Inertia

What two factors affect the amount of gravitational pull between two objects?

• Mass and Distance
• Inertia and Mass
• Mass and Weight
• Inertia and Weight

What two factors keep the planets in orbit around the sun?

• Sun's inertia and Planet's mass
• Planet's inertia and Sun's gravity
• Planet's gravity and Sun's inertia
