1961
1995

1969
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.
Albert Einstein, in 1945
Aristarchus of Samos, in 280 BC
Steven Hawking, in 2000
Galileo Galilei, in 1584
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
Chinese robot on Neptune
Curiosity rover on Mars
Voyager 1
Hubble telescope
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?
2004
1609
210 BC
1845
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
Venus
Mercury
Neptune
Mars
8. Imagine Earth was 1 meter in diameter, how big would the sun then be, if the ratio was kept the same?
3 meters
12 meters
109 meters
5.8 meters
9. Who discovered the moon?
Socrates
probably some animal millions of years ago
Isaac Newton
Albert Einstein
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?
Titania - Uranus
Ganymede - Jupiter
Deimos - Mars
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
Saturn
Earth
Mercury
Jupiter
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
ISS
Paris
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
earth would "explode" and shatter into pieces
it would create a large crater and possibly destroy most houses in close proximity
it would kill all life on earth and completely sterilise the planet
it would burn up in the upper atmosphere like a shooting star
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?
2
3
12
7
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

2 tons
64 grams
120 kg
4 million tons
