Geocentric model
This artistic representation of the geocentric model shows signs of the zodiac and the solar system with world at centre.

The Earth-centered Universe of Aristotle and Ptolemy held sway on Western thinking for almost 2000 years.
You can now build your scale model. You can do this with a long tape measure, or you can measure the size of your pace and walk it off counting the number of steps you take.
MODELING THE STRUCTURE OF THE SUN
Lacking any direct measurements of the solar interior, astronomers must use more indirect means to probe the inner workings of our parent star.
Modeling Magnetic Fields
Magnetic field lines loop through the solar atmosphere and interior to form a complicated web of magnetic structures.

A description of the structure and organization of the data in a database. Specifically, the Data Model makes explicit the tables names, their contents, and how they are related to, and linked with, one another.
More Models of the Universe
We've seen what Newton thought of the Universe, but what did modern astronomers think of it? By modern I mean astronomers working over the past 100 years.
Unified model
Astronomers have identified a dozen or so types of AGN, each with a different overall pattern of emission.
Babcock model: A model of the sun's magnetic cycle in which the differential rotation of the sun winds up and tangles the solar magnetic field in a 22-year cycle. This is thought to be responsible for the 11-year sunspot cycle.

Modelling of Tau Ceti's dust disk observations by the astronomers indicate, however, that the mass of the colliding bodies up to 10 kilometers (6.2 miles) in size may total around 1.2 Earth-masses, compared with 0.

Models of an evolving population with various SFR histories can also predict broad-band colors as well as EW(Ha); it turns out the Ha is vastly more sensitive to bursts of small relative mass.
Models of protostar also show that they will have accretion disks and jets. The jets are not long-lived and last only about 100,000 years.

Modeling simulations by Wilner's team suggested that the semimajor axis of the planet's orbit may center around 30 AUs. The simulations also indicated that the planet must be smaller than 30 times Jupiter's mass.
Models of the Rio Cuarto event suggest that the object struck at an angle of no more than 15 degrees from the horizontal, with the impact itself having 10 times more explosive energy than the Barringer event and 30 times more than the Tunguska event.
A model of the Sun shows its nuclear fusing core (where hydrogen is turned into helium by the conversion of mass into energy), an envelope where energy is transferred by radiation, and an outer layer where convection (the rising of hot gases, ...
A model for the universe in which a repulsive force counteracts the attractive force of gravity, driving all the matter in the universe apart at speeds that increase with time.
A model that offers a logical explanation for the law of multiple proportions and the law of constant composition by stating that all elements are composed of atoms, all atoms of a given element are identical, ...
A model universe in which the average density is great enough to stop the expansion and make the universe contract.

The model shows how proposed underground reservoirs of pressurized liquid water above 273 degrees Kelvin could fuel geysers that send jets of icy material into the skies above the moon's south pole.
Two models to explain this puzzle have been proposed. In the disk model, the gravity of a dense disk of gas around Sgr A* offsets the tidal forces and allows stars to form; in the migration model, ...
This model of Mariner 10 shows the spacecraft as it appeared during flight.
This model predicts that there should be many dead quasars lurking at the cores of galaxies. Astronomers are beginning to find the inactive supermassive black holes in some galaxies.
Some models allow alignment on ANY catalogue object, which is helpful, but I find that accuracy is best on stars or very round objects. I find that planetary positions are especially suspect. The computer carries only the date, not the hour.
Open models can have an age for the universe ranging from the Hubble time down to 2/3 the Hubble time. The flat model has an age exactly equal to 2/3 the Hubble time, and the closed models have ages less than this.

Closed models of the universe have Ω > 1, flat models have Ω = 1, open models have Ω < 1. Omega can be broken into two components: Ωm and Ωv, which represent density of matter and dark energy.
