By its movement. That means that more than one observation is required - for example, comparison of photographs made on different days.
we have to distinguish between firefighting and fire alarm system. fire fighting is mechanical work (either sprinkler system or Foam or CO2 or FM200) and there is fire alarm or detection system this is an electrical thing that includes ( detectors an fire alarm system) for electrical control building we use FM200.
There are several different manufacturers of industrial robots, and each manufacturer uses their own naming/numbering system to distinguish different product lines.
odbms stands for Object DataBase Management System & ordbms stands for Object Relational DataBase Management System odbms supports complex data-types. ordbms is one of the two approaches derived from odbms.(second one is oodbms). ordbms can be thougth of as an attempt to extend rdbms.
Solar System models, especially mechanical models are called orreries.
There are a lot of astronomers in that case who has contributed a lot in astronomy and astrophysics. Naming a few whose contributions are very very important and fascinating ,the astronomers are as follows- Galileo Galilei-one of the revolutionary inventors of his time he was the one who thought of using the telescope for astronomical purposes.which not only supported the heliocentric model but also gave us the glimpses of our own solar system. Sir Isaac Newton-Even though a great scientist was not able to contribute so much to astronomy ,gave us the universal law of gravity and the basics idea of the reflector telescope(now known as newtonian reflector). Johannes Kepler-one of the great contributors with the help of the data collected by his mentor Tycho Brahe gave the structure of solar system with just observations aided by eyes. There are a lot of people who has contributed in the field of astronomy ,but due to insufficient space I'm not able to mention.

Mainly astronomers. But cosmologists and astrophysicists will also be interested in outer space.
Astronomers Believe That The Solar System Began As A Huge Cloud Of Dust And A Gas Called ''NEBULA''
Astronomers must learn physics, chemistry, mathematics and computer science...and how to use a telescope, astronomers must rely on their observation skills, for instance physics has helped astronomers to understand what makes spiral galaxies have spiral shapes, another is Spectroscopy which is the use of light from a distant object to work out the object is made of, When something is moving away from you, it stretches that waveform, while if it moves towards you it compresses the signal wavelength it emits. Spectroscopy also tells you a star's temperature, mass and surface gravity.

When exploring space, astronomers use astronomical units, (AU) to measure the distance from one object to another. Since every distance from one object in our solar system to another object in our solar system, the distance of a planet from the sun would be measured in astronomical units

Many astronomers, historians, regular people, and scientisis know about the planets in our Solar system.
