2005 VX3

2005 VX₃ is the minor planet with the largest known heliocentric semi-major axis and aphelion. Additionally its perihelion lies within the orbit of Jupiter, which means it also has the largest orbital eccentricity of any known minor planet. 2005 VX₃ has a barycentric semi-major axis of ~1026 AU.2012 DR30 has a larger barycentric semi-major axis.

2005 VX₃ has a short observation arc of 81 days and does not have a well constrained orbit. It has not been observed since January 2006, when it came to perihelion, 4.1 AU from the Sun. It may be a dormant comet that has not been seen outgassing. In the past it may have made closer approaches to the Sun that could have removed most near-surface volatiles. The current orbit crosses the ecliptic just inside Jupiter's orbit and has a Jupiter-MOID of 0.8 AU.

As of 2016, it has an apparent magnitude of ~27 and is 22 AU from the Sun. It would require one of the largest telescopes in the world for any more follow-up observations.

Sony CCD-VX3

Sony 3CCD-VX3 (often referred to as simply VX-3) was a Hi-8 camcorder noteworthy for being the first to feature dichroic (prismatic) imaging. It was released to the North American market in 1993 at a street cost of about US$3500. The PAL version as well as the Japanese version had the model name CCD-VX1.

The image is created using three 1/3" CCD chips by prismatically splitting the optics into red, green, and blue, and processing each of these channels individually; this preserves quality especially with red hues. The camera imaged in 410,000 pixels with horizontal resolution of better than 530 lines.

During the mid-1990s, Sony dropped Hi-8 in favor of the emerging DV format, and as a result the VX-3 was discontinued in September 1995. However the VX-3 went on to serve as the framework for a line of professional DV cameras, including the DCR-VX1000, DCR-VX9000, and DSR-200.
