A virus is basically DNA or RNA (single- or double-stranded)surrounded by a protein capsule.
Typically the protein coat, or capsid, of an individual virus particle, or virion, is composed of multiple copies of one or several types of protein subunits, or capsomeres. Some viruses contain enzymes, and some have an outer membranous envelope. Many viruses have striking geometrically regular shapes, with helical structure as in tobacco mosaic virus, polyhedral (often icosahedral) symmetry as in herpes virus, or more complex mixtures of arrangements as in large viruses, such as the pox viruses and the larger bacterial viruses, or bacteriophages . Certain viruses, such as bacteriophages, have complex protein tails.
The inner viral genetic material -the nucleic acid- may be double stranded, with two complementary strands, or single stranded; it may be deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). The nucleic acid specifies information for the synthesis of from a few to as many as 50 different proteins, depending on the type of virus.
A typical virus is made up of a core of genetic material, either RNA or DNA. It is engulfed by a protective coat referred to as a capsid which is made up of protein.
The helical virus is a type of virus that has a capsid structure in the shape of a helix. This helical structure is formed by protein subunits arranged in a spiral around the viral genetic material. Examples of helical viruses include tobacco mosaic virus and influenza virus.
The coating of a virus is made of protein molecules. These proteins can vary in composition and structure, helping the virus to attach to host cells and invade them.
Without the "object" it is impossible to answer this question.
An electron microscope is used to observe the structure of a virus. This powerful microscope is capable of providing detailed images of viruses at a nanometer scale due to its high magnification capabilities.

A typical virus can weigh anywhere from a few femtograms to a few nanograms, depending on the type and size of the virus. On average, a typical virus weighs around 10-1,000 femtograms.
