I guess if you belive that UFOs exsist, of course it may be one. It could also just be a bright star.

i really hate it when someone just copies out an encyclopedia article to answer a question.. especially if that article has almost nothing to do with the question.... sheesh.
anywas a bright light in the sky to the west after sunset is venus. it is much brighter than any other planet or star, right now, eventually it will dim down to be less conspicuous.

The planet Venus is the brightest object in the sky (besides the sun and the moon) and at certain points in its orbit in relation to us it can be seen even before sunset and for several hours afterwards.
And by the way, Venus has been around for billions of years, I'm surprised you've never seen it before.

The distance to a star is measured in light-years. A light-year is the distance that light travels in one year. This number is about 6 trillion miles. The nearest star (besides our sun) is 4.24 light-years from earth. This means that light emitted for this star takes 4.24 years to reach earth. Some stars are over millions of light-years away. The closest star is the sun. Beyond that is Proxmia Centauri, at 4.24 light-years away. Alpha Centauri is at 4.37 light-years, and beyond that is Barnard's star at 5.97 light-years away.
A star is a giant ball of gas which releases energy produced by nuclear fusion in its core. Stars are composed of at least 99% hydrogen and helium. These elements are combined by nuclear fusion to create heavier elements, such as carbon.
There are many different types of stars. These include variable stars, supernovae, novae, and others. Each of these stars have their own characteristics that make them unique.
There are many different stages in the lifetime of a star. Usually, it takes up to millions or billions of years to complete these stages. It takes a few million years for a gas cloud to collapse and become a star. Stars that have about 50 times the mass of our sun can last for about 10 million years. On the other hand, stars with 1/100 the mass of our sun can last for up to one trillion years.
Our sun's luminosity is about average as compared to other stars throughout the galaxy. Some celestial objects are up to 600,000 times as bright, while others are 1/550,000 as bright. Generally though, stars range from being 1/10,000 times as bright to 10,000 times as bright as our sun. Brightness is measured in magnitude. Apparent magnitude (m) is determined by distance and absolute magnitude (M). Apparent magnitude is basically how bright it appears on earth. Absolute magnitude is how bright the object would be if view from 10 parsecs away (about 32 light-years).
There is a simple system used to express the difference between magnitudes. A magnitude 1 (written 1m) is about 2.5 times as bright as a 2m, a 2m is about 2.5 times ad bright as a 3m, and so on. In the end, a 0m is exactly 100 times as bright as a 5m. An object with a magnitude of six is the dimmest the naked eye can see. Some objects are so bright that their magnitude is negative. For example, Venus has a magnitude of -4, and the sun's magnitude is -27!
