General info
What is the hottest planet in our solar system?
What are the components of Earth's atmosphere?
Earth's atmosphere is 78 percent nitrogen, 21 percent oxygen and 1 percent other ingredients—the perfect balance to breathe and live.
What was the device used to observe celestial bodies before any missions left put in space?
Telescope
Which are the two ice giants?
Uranus and Neptune
What is the largest moon in the solar system?
Ganymede
This is a small rocky planet which is the close to the Sun. It has an extreme temperature range. Some scientist think volcanoes are active on this planet.
MERCURY
What is Saturn's atmosphere made up of?
Hydrogen and Helium
What are the two missions on the planet Earth?
Terra and Aqua
Jupiter, Saturn, Uranus, and Neptune are commonly known as
The gas giants
How many moons does Saturn have?
82
This is a cold planet and lifeless with permanent ice caps. It is often called the "Red planet." The first spacecraft (Mariner 4) landed on it in 1965.
Mars
What 3 main elements are the Gas Giants composed of?
Hydrogen, Helium.
Which spacecraft has visited Neptune?
NASA's Voyager 2 is the only spacecraft to have visited Neptune up close. It flew past in 1989 on its way out of the solar system.
What is one thing that all the 4 outer planets have in common?
They are made of gas and they have rings.
What are the four largest moons of Jupiter?
Io, Europa, Callisto, and Ganymede
What's unique about Uranus' orbit?
It rotates at a nearly 90 angle form the plane of its orbit. This unique tilts makes Uranus appears to spin on its side.
Why is Mars known as The Red Planet?
Mars is known as the Red Planet because iron minerals in the Martian soil oxidize, or rust, causing the soil and atmosphere to look red.
What are the names of the two missions that are on route to Mercury?
The two spacecraft of ESA-JAXA's BepiColombo are en route to Mercury.
Through mathematical calculations
What are the planets that don't have any moons?
Venus and Mercury
What are the names of the four dwarf planets and where are they located?
Ceres, Pluto, Haumea, Makemake and Eris. Ceres is located inside the asteroid belt between the orbits of Mars and Jupiter, while the other dwarf planets are located in the outer solar system in, or near to, the Kuiper belt.
Why wouldn't you want to be on Mercury's atmosphere?
Mercury's thin atmosphere, or exosphere, is composed mostly of oxygen (O2), sodium (Na), hydrogen (H2), helium (He), and potassium (K). Atoms that are blasted off the surface by the solar wind and micrometeoroid impacts create Mercury's exosphere.
What was the first successful mission to Mars and when was it?
The first true Mars mission success was the Mariner 4 flyby in 1965.
What's unique about Uranus' and Venus' rotation?
They both rotate east to west. But Uranus is unique in that it rotates on its side.
What does a moon need to be suitable for life?
One factor determining a moon's suitability for life is the stability of its orbit, which can be disrupted by the close proximity of its sun. It also certainly needs an atmosphere. To have enough gravity to hold onto an atmosphere, it obviously must be larger than Earth's own airless Moon
