List 25 things that would be different during your lifetime because of this change?

Question

If the Orbit of the Earth Were 5% Smaller (a = 0.95 au) than it is today (a = 1.0 au).

Answer 1

I'd have to get a new calendar.

Answer 2

IF the smaller earth is in the same distance to the sun:
Please note: Some of the following answers may not relate to each other.

1: Less overall population

2: History will be different with less wars and poverty

3: Geographical land makeup would be different.

4: The dinosaurs may still exist today because the asteroid would have missed the smaller earth

5: We might not exist due to the dinosaurs that may roam the earth

6: organisms may be of alien form

7: Colder climates

8: The moon might be further away due to the earth's weaker gravity

9: The earth's oceans may not have tides as strong as it is today

10: More land than ocean on Earth

11: The smaller earth might suffer less pollution

12: Global warming would be uncommon

13: Ice Ages will arrive but not as frequent

14: Less earthquakes and volcanoes

15: There would be less Marine species

16: The speed of the earth's rotation might be slower

17: Longer days and nights

18: We would be younger due to longer days and nights

19: We would weigh less

20: If the moon is still around, then the rotation of the earth will be slower due to strong tidal breaking

I couldn't think of any more!

Answer 3

If the orbit of Earth were 95% the distance from Earth to Sun than it is today:

1.- Assuming a circular orbit, the current mean distance (149.5 millions of kilometers) from Earth to Sun will be 142 millions.
2.- The Year duration would be 347 days instead of (hot days will be hotter (Earth is closer to Sun)
3.- Total solar eclipses will never ocurr
4.-We have to change the Christian calendars around the Occidental World
5.- Maybe there would not be frozen Polar regions in Earth
6.- Less available water
7.- More desertic regions
8.- Another plant species on Earth
9.- Another animal species on Earth
10.- Hotter summers
11.- A more intense Greenhouse effect
12.- Maybe we were living underwater
13.- There would be more violent hurricanes
14.- There would be more droughts
15.- Maybe no food availability on the Earth's surface
16.- Maybe just aquatic supply food
17.- Maybe we will need special equipment for walking on emerged lands.
18.- We will see a bigger Sun
19.- Sunlight would travel in 7 minutes 53 seconds instead of currently 8 minutes 18 seconds
20.- If we could survive on Earth surface we may have evoluted as creatures for living in deserts (as camels do for example)
21.- If we could live technologically as in present day we may need more conditioning air everywhere
22.- We would be passive beings in order to save water.
23.- More people would be living near the Poles instead of the Equator.
24.- We could use more solar energy to survive instead of carbon energy (oil for example)
25.- At 5% nearer to the Sun not necessarily we will die according to current theories of habitability zones proposed by Morrison and Drake (1959-1961) but our aspect and way of life will be definitively altered.

Good luck!

Answer 4

Massive changes, including possibly no life (as we know it) would exist. Being closer to the sun would mean most likely a greater gravity, more heat, more violent weather, and possibly a different atmosphere.

Answer 5

We'd be closer to the Sun

Answer 6

1. We are all dead

2 - 25 don't matter after number 1 above.

Answer 7

A solar eclipse wouldn't be nearly as exciting.

Answer 8

2. The size of an a.u. would be smaller.

Answer 9

thn i dont think we'd be earth. we'd be a planet closer to the sun. no???

Answer 10

1. we would all be older than we are right now.
