Actually are slowly moving away from . But the effect is very small, only about 0.01% in a billion years for Earth.

There are two main mechanisms driving the planets away from the Sun, according to http://curious.astro.cornell.edu/about-us/41-our-solar-system/the-earth/orbit/83-is-the-distance-from-the-earth-to-the-sun-changing-advanced.

First is the tidal friction effect. The Sun rotates on average about once per thirty Earth days (the Sun is not rigid and its rotation rate varies with latitude). The Earth takes about 365 days to orbit the Sun. As is better known with the Earth versus the Moon, the difference in periods of rotation and revolution means tidal friction transfers energy from the faster cycle (Sun rotating) to the slower one (Earth orbiting). So the Sun is gradually slowing its rotation and the Earth is slowly moving outward. The other planets are moving outward for the same reason. But the Sun is rather far away and its rotation is too slow to have a major impact. The source quoted above states that the tidal effect is pushing the Earth away from the Sun at only about one micrometer per year.

The second effect reported by Cornell University’s site is the loss of mass the Sun experiences as hydrogen is fused to helium. The helium has less mass than the hydrogen it comes from, and the difference is the energy output from the Sun, according to Einstein’s formula ##E=mc^2##. The decreasing mass of the Sun is pushing the Earth away at about 1.5 cm per year, a much stronger interaction than the tidal effect. But it still amounts to only a change of 0.01% in a billion years.

With the recent verification of gravitational waves, we know that gravitational wave emission is tending to make the planets spiral inwards. But gravitational wave emission has almost no impact on the motion of the planets. Planets are moving so slowly and with such weak gravitational interactions that gravitational wave emission is ten orders of magnitude less than the direct effect of the Sun losing mass.

All told, the net result is the planets are moving away from the Sun, but only very slowly. As noted above, the dominant effect amounts to only 0.01% in a billion years for Earth.

You are required to write a complete laboratory report that covers the drinking water quality experiment from “Lab 2: Water Quality and Contamination,” using knowledge gained throughout the course. Use the instructor feedback on your Rough Draft from Week Three to guide your writing. Be sure to download the Final Lab Report Template and utilize this form (not the Rough Draft template) to ensure proper formatting and inclusion of all required material. Additionally, view the Sample Final Lab Report before beginning this assignment, which will illustrate what a Final Lab Report should look like. You must use at least two scholarly sources, two other highly credible sources, and your lab manual to support your points. The report must be six to ten pages in length (excluding the title and reference pages) and formatted according to APA style. For information regarding APA samples and tutorials, visit the Ashford Writing Center, located within the Learning Resources tab on the left navigation toolbar, in your online course.

The Final Lab Report must contain the following eight sections in this order:

1. Title Page – This page must include the title of your report, your name, course name, instructor, and date submitted.
2. Abstract – This section should provide a brief summary of the methods, results, and conclusions. It should allow the reader to see what was done, how it was done, and the results. It should not exceed 200 words and should be the last part written (although it should still appear right after the title page).
3. Introduction – This section should include background information on water quality and an overview of why the experiment was conducted. It should first contain background information of similar studies previously conducted. This is accomplished by citing existing literature from similar experiments. Secondly, it should provide an objective or a reason why the experiment is being done. Why do we want to know the answer to the question we are asking? Finally, it should end the hypothesis from your Week Two experiment, and the reasoning behind your hypothesis. This hypothesis should not be adjusted to reflect the “right” answer. Simply place your previous hypothesis in the report here. You do not lose points for an inaccurate hypothesis; scientists often revise their hypotheses based on scientific evidence following the experiments.
4. Materials and Methods – This section should provide a detailed description of the materials used in your experiment and how they were used. A step-by-step rundown of your experiment is necessary; however, it should be done in paragraph form, not in a list format. The description should be exact enough to allow for someone reading the report to replicate the experiment, however, it should be in your own words and not simply copied and pasted from the lab manual.
5. Results – This section should include the data and observations from the experiment. All tables and graphs should be present in this section. In addition to the tables, you must describe the data in text; however, there should be no personal opinions or discussion outside of the results located within this area. 
6. Discussion – This section should interpret your data and provide conclusions. Discuss the meanings of your findings in this area. Was your hypothesis accepted or rejected, and how were you able to determine this? Did the results generate any future questions that might benefit from a new experiment? Were there any outside factors (i.e., temperature, contaminants, time of day) that affected your results? If so, how could you control for these in the future?
7. Conclusions – This section should provide a brief summary of your work.
8. References – List references used in APA format
