A planet (from Ancient Greek αστήρ πλανήτης (astēr planētēs), meaning "wandering star") is a celestial body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighbouring region of planetesimals. The term planet is ancient, with ties to history, science, mythology, and religion. The planets were originally seen by many early cultures as divine, or as emissaries of deities. As scientific knowledge advanced, human perception of the planets changed, incorporating a number of disparate objects. In 2006, the International Astronomical Union (IAU) officially adopted a resolution defining planets within the Solar System. This definition has been both praised and criticized, and remains disputed by some scientists since it excludes many objects of planetary mass based on where or what they orbit.
The planets were thought by Ptolemy to orbit the Earth in deferent and epicycle motions. Although the idea that the planets orbited the Sun had been suggested many times, it was not until the 17th century that this view was supported by evidence from the first telescopic astronomical observations, performed by Galileo Galilei. By careful analysis of the observation data, Johannes Kepler found the planets' orbits to be not circular, but elliptical. As observational tools improved, astronomers saw that, like Earth, the planets rotated around tilted axes, and some shared such features as ice caps and seasons. Since the dawn of the Space Age, close observation by probes has found that Earth and the other planets share characteristics such as volcanism, hurricanes, tectonics, and even hydrology.
Data ( /ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) are values of qualitative or quantitative variables, belonging to a set of items. Data in computing (or data processing) are often represented by a combination of items organized in rows and multiple variables organized in columns. Data are typically the results of measurements and can be visualised using graphs or images. Data as an abstract concept can be viewed as the lowest level of abstraction from which information and then knowledge are derived. Raw data, i.e., unprocessed data, refers to a collection of numbers, characters and is a relative term; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data refers to raw data collected in an uncontrolled in situ environment. Experimental data refers to data generated within the context of a scientific investigation by observation and recording.
The word data is the plural of datum, neuter past participle of the Latin dare, "to give", hence "something given". In discussions of problems in geometry, mathematics, engineering, and so on, the terms givens and data are used interchangeably. Such usage is the origin of data as a concept in computer science or data processing: data are numbers, words, images, etc., accepted as they stand.

First Corinthians 9:24-27
Here is my heart take what you want
'Cause I have no use for it anyway
Well of all the stupid things I've ever said
This could be the worst may be the best
But those are the breaks
These are the bruises
And if I can't give myself away I'm the only one who loses
And I don't want to lose this
It is the sea that makes the sailor
And the land that shapes the sea
And I do not know yet what I am made of
Or all I may someday be
And it is the wood that makes a carpenter
It's the very tools of his trade
And it is love that makes a lover
And a cross that makes a saint
Here is my song, listen if you will
But I have no heart for it anymore
I just have half a mind to cut it loose
And if it sails off into the blue
Then I'll just let it soar
And the sky is better keeping
And I won't be any poorer
For giving it its freedom
And here's one for freedom
It is the sea that makes the sailor
And the land that shapes the sea
And I do not know yet what I am made of
Or all I may someday be
It is the wood that makes a carpenter
It's the very tools of his trade
And it is love that makes a lover
And a cross that makes a saint
Well, of all the stupid things I've ever said
This could be the worst may be the best
