2. Why do we need to continue to research new planets
2.1. Research and prepare experiment
3. Bigger types of planets called "super- earths" are very common in our galaxy such as some exo planets some planets could be made of iron and rock which is similar to earth but may have a flaw for humanity to move and adapt to a new invionment
4. Examples on how mars is similar to earth: Mars length of day is 24hours and 37 minutes the normal day time on earth is 23 hr and 56 minutes as you can see and visualize earths time is very similar to mars. Earth travels 18.5 miles per second and mars travels 14.5miles per second earths is 4 miles faster per second. If you were to wheigh 100 pounds on earth you would whiegh 38 pounds on mars because of the low amount of gravity there is. Which cause height differences
5. Bad news fellow earthlings one day we must abandon this planet we call earth because we are killing it by killing I mean dying it out draining its resources, because of pollution 75% of this planet has little resources for new coming generations in a 100 years from now we may not be able to survive. . scientist have found thousands and thousand of exo planets compatible to earth and hundred of "super earths" such as Gisele 581g which was discovered in September 2010 which is highly compatible to earth its is only one of the the few plants capable of hosting life we have so much to discover yet we discovered so much.
6. With little resources we may need to leave and leaving may be a hard but since we have so much discover and so many years to figure out what else might be out there there is hope for a planet so very similar like ours for living and this new planet we must not destroy we may one day find more galaxy's and discover so much more for humanity
7. created inventions to help discover more about size and mass.
7.1. Midterm
8. SImilar Planets
9. 30 years ago only nine planets were found in our solar system astronomers have found more than a thousand exo planets circling the sun
10. People have invented telescopes such as the Kepler and the splinter which can see exo planets and many many other which can also find the the most accurate size according to the information it receives. The info "seize mic waves"
11. what we have discovered over the years compared to the the past
