China
3. In what year was this first accomplished?
1969
1961
1995
1952
4. Who first introduced the idea of the heliocentric model - the theory that not earth, but the sun is the center of the solar system?
in 1543, Nicolaus Copernicus published a scientific paper "proving" the heliocentric model (Which was accepted and more thoroughly proven by Galilei. The theory however was much older, even though it got little attention back then.
Steven Hawking, in 2000
Aristarchus of Samos, in 280 BC
Galileo Galilei, in 1584
Albert Einstein, in 1945
5. What manmade object is the furthest from earth?
Mars is 145 million km away, Hubble is in Earth's orbit 568 km high, there is no and never has been a robot on Neptune, Voyager 1 is 22 billion km away
Voyager 1
Curiosity rover on Mars
Hubble telescope
Chinese robot on Neptune
6. Johannes Kepler discovered and proved, that planets move around the sun in elliptical orbits and not in perfect circles. When did he publish his paper?
1609
1845
2004
210 BC
7. What planet is most similar in size to earth?
Earth is 5% bigger than Venus, 88% bigger than Mars and only 26% the size of Neptune
Neptune
Mars
Venus
Mercury
8. Imagine Earth was 1 meter in diameter, how big would the sun then be, if the ratio was kept the same?
109 meters
12 meters
3 meters
5.8 meters
9. Who discovered the moon?
probably some animal millions of years ago
Albert Einstein
Socrates
Isaac Newton
10. Pluto is much further from the sun than Earth is. Does that mean its orbital velocity (how fast it moves relative to the sun) is faster, or slower than Earth's?
Pluto moves much slower. The further an object is away from the sun, the slower it has to move to maintain a stable orbit, since gravity weakens over distance.
Pluto moves faster
Pluto moves slower
11. What is the biggest moon in the solar system?
Deimos - Mars
Titania - Uranus
Ganymede - Jupiter
Earth's moon
12. Which planet has the biggest moon relative to its own size? - in other words: Which planet is most similar in size to its biggest moon?
by far
Mercury
Earth
Jupiter
Saturn
13. If the Sun was replaced by a black hole of equal mass, the Earth would be sucked in pretty quickly
nothing would change for Earth's orbit, since it depends solely on gravity, not the type of object it orbits.
False
True
14. There are more stars in the (observable) Universe than there are grains of sand on Earth
an estimated 10^18 grains versus an estimated 10^23 stars in the universe
True
False
15. Say the International Space Station crosses directly over Berlin. Is Berlin then closer to the ISS or to Paris?
Paris is 900km South West, while the ISS is only 400 km above
Paris
ISS
16. What would happen if an asteroid, 200km in diameter, would hit earth directly?
All life on Earth, be it in the best Bunker, the deepest ocean or in the air would die either immediately or shortly after - including all bacteria
it would kill all life on earth and completely sterilise the planet
it would create a large crater and possibly destroy most houses in close proximity
it would burn up in the upper atmosphere like a shooting star
earth would "explode" and shatter into pieces
17. Neptune is the furthest planet from the sun. Earth is the 3rd closest. Is Earth closer to the Sun or to Neptune?
When Earth and Neptune are on the same side of the Sun, the closest they get to each other is 4.3 billion km. The Sun is only 150 million km away.
Sun
Neptune
18. How many men have walked on the moon?
3
7
2
12
19. With current technology, in a perfectly planned mission, it would take about 2 months to get from Earth to Mars.
Because of the minimum distance of 55 million km it takes 6 to 8 months of traveling to get there.
False
True
20. The Sun is producing/converting a lot of energy by fusing atoms together. How much mass does the Sun lose because of fusion per second?
4 million tons
2 tons
64 grams
120 kg
