How long would it take a human currently on Earth to reach Ceres? Currently, we have no capability to even go back to the Moon, let alone any farther. A reasonable estimate would be 25 years from the time somebody decides to go back into space beyond Low Earth Orbit. The trip itself would take about 2.5 years, depending on the type of propulsion and the urgency of the mission.
The NASA space probe Dawn was launched in 2007 to study both Ceres and Vesta. Using very low-powered ion engines, Dawn arrived near Vesta in 2011, spent nearly 2 years orbiting Vesta, and arrived in Ceres orbit in early 2015.

Ceres rotates on its axis with a period of about 9 hours.
365.25 days
The distance to Ceres varies depending on the relative positions of Earth and Ceres in our orbits. As of April 25, 2010, at 3:07 PM PDT, Ceres is at a distance of 2.158218 AU, where each AU is about 500 light-seconds. (One AU is the average distance between the Sun and the Earth.) So Ceres is currently 1079 light-seconds away. The orbit of Ceres around the Sun is an ellipse with aphelion of 2.98 AU and perihelion of 2.55 AU. When the Earth is on one side of the Sun and Ceres is on the other, our distance apart is about 3.98 AU, and when Ceres and the Earth are closest together, we are only about 1.55 AU distant. You can download the free open-source planetarium program Stellarium to see a representation of the sky and calculate the distance to any astronomical object in its database. And if you can see it, it's in there!
It takes Ceres approximately 4.6 Earth years, or about 4 years and 220 days, to complete one orbit around the Sun.
It takes approximately 23 years to travel from Earth to Ceres.
