Hubble's law concerning objects in space states that:
1. The farther the object, the faster it appears to be moving away.
2. The smaller the object, the faster it appears to be moving away.
3. The closer the object, the faster it appears to be moving away.
4. The bigger the object, the faster it appears to be moving away.
